Question 198971: consider the following function
f(x)=4x^3+x^2-0.06x+7
find the two points on the graph at which the tangent line is horizontal. Give your values
(-----,-----) point with smaller x value
(-----,-----) point with larger x value
can someone help please
thanks

Take the first derivative of your function, set it equal to zero, and solve the quadratic equation.
=4x^3+x^2-0.06x+7)
 = 12x^2 + 2x = 0.06)
Solve for 
using the quadratic formula to get your two 
-coordinates. Then evaluate )
and )
to get your two 
-coordinates.
