Question

Help!!!
Find the derivative of f(x) = 5x + 9 at x = 2.

Answer 1

so the answer is 5

Answer 2

oh ok so would the answer be zero since f(2) does not exist

Answer 3

that's wrong.

Answer 4

if your derivative is 5 then you the function y=5 for the derivative

Answer 5

what do i do im confused, f2 dont exist i get that now what do i do next

Answer 6

which means the value of the derivative is 5 for every x within the domain of the function

Answer 7

so it is 5, can you also help me with f(x) = -6/x at x = 12.

Answer 8

basically your derivative looks like this
