If you have the following function f ( x ) = 2 x + 7, compute f (0), f (-4), f (5), f (-9).
A) f (0) = 10, f (-4) = -3, f (5) = 20, f (-9) = -13
B) f (0) = 7, f (-4) = -1, f (5) = 17, f (-9) = -11
C) f (0) = 6, f (-4) = -0, f (5) = 16, f (-9) = -10
D) f (0) = 8, f (-4) = -2, f (5) = 18, f (-9) = -12
E) f (0) = -7, f (-4) = 1, f (5) = - 17, f (-9) = 11

To find the value of the function for each given x, substitute x into the function and solve: f(0) = 2(0) + 7 = 7, f(-4) = 2(-4) + 7 = -8 + 7 = -1, f(5) = 2(5) + 7 = 10 + 7 = 17, f(-9) = 2(-9) + 7 = -18 + 7 = -11.
