Question

What is the slope of the line tangent to f (x) = 2x^2 - 2x - 3 at x = -1 ?

Answer 1

find the derivative of the function

then substitute x = -1 into the deriviate to find the gradient of the tangent at x = -1

Answer 2

as he said ^^^^^

Answer 3

How to find the derivative of this function?

Answer 4

Use the Power Rule

Answer 5

I don't know about power rule

Answer 6

Where did you get this problem if you don't know how to do a derivative?

Answer 7

from KhanAcademy

Answer 8

You need to learn how to do a derivative to be able to do this problem. KA has some good videos on derivatives.

Answer 9

2x^2 - 2x - 3= 4x-2 <----- THis is the derivative

Answer 10

I only know how to take slope of a line but in this case it is a function not lines

Answer 11

This is an introductory calculus problem, you need to learn about derivatives first.

Answer 12

okay thanks

Answer 13

someone look at my last question please I'm desperate
