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.







Solve for using the quadratic formula to get your two -coordinates. Then evaluate and to get your two -coordinates.
