For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact.

y=4/3x^3-7x+5

Step 1

To locate the points on the graph where the tangent is parallel to the x -axis

Step 2

The tangent to y = f(x) at a point (a,, f(a) ) has slope f'(a) ( derivative ...
