Question

Consider the function f(x)=-5x^2 +2x -8. find the critical point a of the function

Answer 1

To find the critical number of that function we have to find the derivative and set it equal to 0 and solve for x.  The derivative of the function is f'(x)=-10x+2.  If we set it equal to 0 and solve, we have x = -2/-10 which simplifies to x = 1/5.
