If you have the following function f ( x ) = 9x + 7, compute f (1), f (-3), f (4), f (-6).
A. f (1) = 19, f (-3) = -22, f (4) = 46, f (-6) = -49 B. f (1) = 16, f (-3) = -20, f (4) = 43, f (-6) = -47 C. f (1) = 15, f (-3) = -19, f (4) = 42, f (-6) = -46 D. f (1) = 17, f (-3) = -21, f (4) = 44, f (-6) = -48 E. f (1) = -16, f (-3) = 20, f (4) = - 43, f (-6) = 47
