1.) P(2, 4) lies on the graph of y=x4-2x-4

Q is the point (x, x4-2x-4)

Write an equation for the slope of the secant line through P and Q as a function of x.

2.) Using the formula above, find the slopes fo 1.9, 1.99, 1.999, 2.001, 2.01, and 2.1 (round 4 decimal places)

3.) What is the slope of the tangent line to the curve y=x4-2x-4 at P(2, 4)

Can you please explain in detail how to get the answers?
