Multiple Choice

Let f be the function defined by f (x) = 4x + 8. Find f (1) , f (- 1) , f (a) , f (- a) , and f (a + 1) .

A) f (1) = 11, f (- 1) = 5, f (a) = 4a + 8, f(- a) = - 4a + 8
B) f (1) = 10, f (- 1) = 6, f (a) = 12, f(- a) = 4, f (a + 1) = 4a + 12
C) f (1) = 12, f (- 1) = 4, f (a) = a + 8, f(- a) = - a + 8, f (a + 1) = 4a + -4
D) f (1) = 12, f (- 1) = 4, f (a) = 4a + 8, f(- a) = - 4a + 8, f (a + 1) = 4a + 12
E) f (1) = 12, f (- 1) = 4, f (a) = 4a + 8, f(- a) = 4, f (a + 1) = 4a + 8
