Question

If Joe wanted to create a function that modeled a base of 8 and what exponents were needed to reach specific values, how would he set up his function?

A) f(x)=x^8
B) f(x)=log8x
C) f(x)=logx8
D) f(x)=8^x

Answer 1

Joe should use the function f(x) = 8^x to model a base of 8 and the exponents needed to reach specific values.

Step-by-step explanation:

To create a function that models a base of 8 and the exponents needed to reach specific values, Joe should use the function f(x) = 8^x. This is the correct choice because the base is 8 and the exponent is represented by x, which can take on different values. By plugging in different values for x, Joe can find the corresponding values for the function.
