The range of the function f(x) = x + 5 is {7, 9}. what is the function’s domain? {2, 4} {-2, -4} {12, 14} {-12, -14} {0, 5}

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.

The table below shows the function f. determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5]. a. 32 b. -32 c. 25 d. -25
