Consider the function f (x) = -4x2 + 8x - 1. %3D Step 2 of 2: Interpret the meaning of f '(-9) = 80. %3D Answer O The instantaneous rate of change at x = -9 is 80. The average rate of change from x = -9 tox = 9 is 80. O The value of the function evaluated at x = -9 is 80. O The slope of the secant line fromf(-9) to f(0) is 80.

Q: 100x+2y=1 and also 100x-2y=1 What is the value of y? A
