If kim wanted to create a function that modeled a base of 7 and what exponents were needed to reach specific values, how would she set up her function?

f(x) = x^7

f(x) = 7^x

f(x) = log7x

f(x) = logx7

Function would be f(x) : .

Step-by-step explanation:

Given : Function that modeled a base of 7 .

To find :  what exponents were needed to reach specific values, set up function.

Solution : We have given that  modeled of base 7.

By the exponent rule : , where b is base and a is an exponent of a function .

So. Kim can setup function with base 7 and exponent x as .

Therefore ,  function would be  f(x) : .

1st option

Step-by-step explanation:

The domain and range are all real numbers , that is

domain { x | x ∈ R }

range { y | y ∈ R }
