# Answer: 26 # Answer: N I Un Which expression calculates the average rate of change of f (x) from x = 0 to x = 4? Wile E. Coyote falls off a cliff. His height at any time t, 0 S t s 4, ish(t) = -5t2 + 80. With what If lim (20)-f(4) speed does he hit the ground? x+4 X-4 ... go to 40. If lim - f( 4th)-f(4) ... go to - 9. h-0 h If10)-10) .. go to - 3. # Answer: - 1 # Answer: -5 Some values of g (x) are given in the table. The lim /()-1(4) average rate of change of g(x) over the interval *-+4 X-4 - will calculate the [4,9] is -3. What is the value of w? If average rate of change from x to 4 ... X - 2 0 4 go to -5. 9 g(x 3 8 W 11 If instantaneous rate of change at x = 4 ... go to -4. # Answer: 40 # Answer: - 9 Approximate the instantaneous rate of change of A tangent line to the graph of f (x) at the point p(x) at x = -2.5. Graph of p(x): x = a uses the instantaneous rate of change for the slope. Write the equation of the tangent line to f (x) = -x2 +5 at x = 5 and then use the tangent line to approximate f (5.1). @ Virge Cornelius 2021
