Question

 Finding slope locations Let ƒ(x) = 41x - x.
a. Find all points on the graph of ƒ at which the tangent line is
horizontal.
b. Find all points on the graph of ƒ at which the tangent line has
slope - 1/2.

Expert Solution
Step 1

Given information:

fx=41x2-x

Step 2

(a)

To find all points on the graph of ƒ at which the tangent line is
horizontal. first, find the derivative.

f'x=082x-1=0x=182

Substitute to find y,

f182=411822-182=1164-182=-1164

Therefore point is 182,-1164
