Question

Find the derivative of f(x) = 4x + 7 at x = 5.

4
1
5
7

Answer 1

For this case we have the following function:

`f(x) = 4x + 7`
Deriving the function we have:

`f '(x) = 4`
We now evaluate the function for the value of x = 5.
We have then:

`f '(5) = 4`
Answer:
the derivative of f(x) = 4x + 7 at x = 5 is:
4
