If you have the following function f ( x ) = 5 x + 6, compute f (5), f (-5), f (9), f (-9).
A) f (5) = 34, f (-5) = -21, f (9) = 54, f (-9) = -41
B) f (5) = 31, f (-5) = -19, f (9) = 51, f (-9) = -39
C) f (5) = 30, f (-5) = -18, f (9) = 50, f (-9) = -38
D) f (5) = 32, f (-5) = -20, f (9) = 52, f (-9) = -40
E) f (5) = -31, f (-5) = 19, f (9) = - 51, f (-9) = 39

To find f(x), substitute x into the function: f(x) = 5x + 6. For f(5), f(-5), f(9), and f(-9), the calculations are: f(5) = 5(5) + 6 = 31, f(-5) = 5(-5) + 6 = -19, f(9) = 5(9) + 6 = 51, f(-9) = 5(-9) + 6 = -39.
