Question

f(x) = 3x3; x = −1
(a) Use any method to estimate the slope of the tangent to the graph of the given function at the point with the given x-coordinate. (Round your answer to three decimal places.)

Answer 1

First find the derivative.
Then put x = -1 in the derivative and that will be the slope of the tangent at x = -1

Answer 2

Do you know how to take derivatives?
