Hint: If a function has a minimum at x=a, then f'(a) = 0.
local min =
The question says if the function has a local min of at x = what are the values of a and b?
b). which of the tangent lines to the curve in part a has the smallest slope?
Please lead me in the right way i dont care about the answers just tell me how i would find the values a or b
i tried plugging in the value of x into f(X) Then i found the derivative and i got stuck
