How to Find Horizontal Tangents | Calculus 1

We go over finding horizontal tangents of polynomial functions, the general principals apply to all differentiable functions. Specifically, we find the x values where the horizontal tangents occur. To do this, we must differentiate the function in question then set the derivative equal to 0, then solve for x. Where the slope is 0, the tangents are horizontal. #Calculus1 #apcalculus

ANSWER TO PRACTICE PROBLEM:
Horizontal tangents at x = 0, -1, 1
