Question: (6 points) Let f(x) = -5x2 - 2x + 9. We will find f' (x) using the definition f'(z) = lim f(x th) - f(x)

(6 points) Let f(x) = -5x2 - 2x + 9. We will find f' (x) using the definition f'(z) = lim f(x th) - f(x) h-+0 h We break this down into four steps, as follows: STEP 1: Find f(x + h). f(ath) = STEP 2: Find f(a + h) - f(z). f(x + h) - f(z) = STEP 3: Find f( x + h) - f(x) h f(x th) - f(z) h STEP 4: Find f' (x) = lim f(ath) - f(z) h-+0 h f' (x) =
