11. [0/1 Points] DETAILS PREVIOUS ANSWERS HARMATHAP12 9.4.027. MY NOTES ASK YOUR Write the equation of the tangent line to the curve at the indicated point. As a check, graph both the function and the tangent line. y=x34X2+9atx=1 X 12. [/2 Points] DETAILS HARMATHAP12 9.4.031. MY NOTES ASK YOUR Find the coordinates of points where the graph of f(x) = x3 + 6x2 9x + 10 has horizontal tangents. As a check, graph f(x) and see whether the points you found look as though they have horizontal tangents. (X: Y) = ( ) (smaller X-value) (X, y) = ( ) (larger x-value)
