For the function f and number a, find the function that gives the slope of the secant line, s(x) = 
, for x ? a. Then describe the behavior of the function values as x approaches a. f(x) = 2x2 - 4; a = -1
A. s(x) = 2(x + 1) for x ? -1; as x ? -1, s(x) ? 2 B. s(x) = 2(x + 1) for x ? -1; as x ? -1, s(x) ? 0 C. s(x) = 2(x - 1) for x ? -1; as x ? -1, s(x) ? -4 D. s(x) = 2(x - 1) for x ? -1; as x ? -1, s(x) ? -8
