Question: Let f(x) = 9x2 + 4x -5 for x Let f(x) 7x2 -5 9T2 + 4x 5 for < 0, for x > 0. According

Let f(x) 7x2 -5 9T2 + 4x 5 for < 0, for

Let f(x) = 9x2 + 4x -5 for x

Let f(x) 7x2 -5 9T2 + 4x 5 for < 0, for x > 0. According to the definition of the derivative, to compute fl (0) , we need to compute the left-hand limit: f(x) f(0) and the right-hand limit: f(x) f(0) We conclude that f' (0)
