Question

Evaluate the function $f$ at the indicated values. $f(x) = -4x^2 + 2x - 8$ a. $f(-2) =$ b. $f(5) =$ c. $f(-a) =$ (Your answer should be in terms of $a$.) d. $-f(a) =$ (Your answer should be in terms of $a$.) e. $f(a + h) =$ (Your answer should be in terms of $a$ and $h$. Be sure to simplify using distribution. Hint: $(a + h)^2 = a^2 + 2ah + h^2$)

          Evaluate the function $f$ at the indicated values.
$f(x) = -4x^2 + 2x - 8$
a. $f(-2) =$
b. $f(5) =$
c. $f(-a) =$
(Your answer should be in terms of $a$.)
d. $-f(a) =$
(Your answer should be in terms of $a$.)
e. $f(a + h) =$
(Your answer should be in terms of $a$ and $h$. Be sure to simplify using distribution. Hint:
$(a + h)^2 = a^2 + 2ah + h^2$)
