f(x) = 7x3 + x2 - 0.08x + 12

Find the two points on the graph at which the tangent line is horizontal. Give your values correct to 2 decimal places.

( , ) (point with smaller x value)

( , ) (point with larger x value)

thanks so much bob!

I suggest youtake the first derivative, which is slope, set that equal to zero, and solve for x.
