10. I am lost with this one.

Use calculus to prove that the relative minimum or maximum for any function f, as shown below, occurs al x = "(x) = ax + box+ c. a#0 Where will the relative minimum or maximum for the function occur? an infection point O a critical value Determine the derivative of the function fix) . ax" + bix + c Determine the critical values of fix) = ax"+ bx + c. A critical value can occur where [(x)=0 and also where I'(x) does not exist. Since I'(x) is a polynomial there are no x-values who not exist Therefore, the only critical values will be where I'(x) = 0. Solve the equation f(x) =0 for x
