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
