Question

Evaluate the function f (x)  4 • 7x for x  1 and x = 2. Show your work

Answer 1

The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function
`f(x)=4.7^x` for x = - 1 and x 2.

The solution is:

1) For x = - 1


`f(-1)=4. 7^(-1) =4. (1/7)=4/7`

2) For x = 2


`f(2)=4.7^2=4(49)=196`
