The population of a town grew from 20,000 to 28,000. D Some parents are opposed to having coffee served in the high school library. The are the possible values for which x can take for the function to be defined. The boat travels at a rate of 1 foot per second. About how many years has the population of the town been growing? Although the seniors are putting up signs and doing press interviews, the principal of Altamont High School has yet to comment on the matter. Best explained through the graph.
The y-intercept is 0, —3. How many times did the water bug go beneath the water level if the boat traveled a distance of 109 feet? The isotope has a half-life of 8 days. Round your answer to the nearest hundredth. The loudness, L, measured in decibels Db , of a sound intensity, I, measured in watts per square meter, is defined as mc023-1. Which equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake? To sum it up, the function's domain is from negative infinity to -1, then from -1 to 1, and then to infinity.
For rational functions, the domain is usually all real numbers except the values of x for which the denomitator is equal to zero. That usually involves stuff like dividing by zero, taking the square root of a negative number, etc. The continuous growth rate is 15%. In general, to find domain and range, you have to look for places where things are suspicious. Which sentence serves as the best introductory sentence to the above paragraph? I found your question in an online resource. A scientist has a 10-mg sample of a radioactive isotope. The half-life of Fermium-257 is about 100 days.
Then things start going south. Which function is graphed below? The range follows the same idea: it's the set of all y-values of the function. The mathy way of expressing that is -oo, -1 uu -1, 1 uu 1, oo. They also believe that a coffee bar would help make money for the school. After 16 days, how much of the radioactive isotope remains? The same is true for all y-values between 4 and 0.
B Seniors at Altamont High School are working for an unusual cause. For example, given the function The domain of the function is all set of real numbers except the values of x for which. The amount of a sample remaining after t days is given by the equation mc001-1. Therefore, the domain of the function, is all set of real numbers except 2 and 4. A coffee bar, the seniors argue, would make students more likely to visit the library and be tempted to read books.
The degree and the leading coefficient of a polynomial function determine the end behavior of the graph. B Which function has the given properties below? Which function describes the graph shown below? So, the sign of the leading coefficient is sufficient to predict the end behavior of the function. As an added bonus, seniors also claim that they will be much more awake for first period. Then, between -1 and 1, everything's fine, so we have to include it in the domain. The amount of a sample remaining after t days is given by the equation mc004-1.
. The seniors of Altamont High want the administration of their school to add a coffee bar to the library. C Some people wish that they had coffee available before their earliest class. A Cepheid star is a type of variable star, which means its brightness is not constant. The maximum value is 3. What is the approximate loudness of the dinner conversation, with a sound intensity of 10-7, Rajah has with his parents? The domain is the set of all real numbers. A sample contains 60% of its original amount of Fermium-257.
From 0 above, everything is good all the way to infinity. About how old is the sample? A Coffee can be quite stimulating and help students focus. The amplitude of the function is 2. The given function is: We know that the value of the root cannot be negative. What is the absolute magnitude of a star that has a period of 45 days? If the annual depreciation rate is 11%, which equation can be used to determine the approximate current value of the car? The leading coefficient is significant compared to the other coefficients in the function for the very large or very small numbers.
The magnitude, M, of an earthquake is defined to be mc021-1. We can see from the graph that from negative infinity to -4, all is well. Use a calculator and round your answer to the nearest whole number. This means that: Therefore, we can substitute with any value of x that is greater than or equal to x, otherwise, the function would be undefined. The function given is shown in the attached picture.
