Answer
$f(-3) = (-3)(-3) +7$
$f(-3) = 9 + 7$
$f(-3) = 16$
$g(3) = (-7)(3) + 3$
$g(3) = -21 + 3$
$g(3) = -18$
$f(-3) - g(3):$
$ 16 -(-18)= 34$
Work Step by Step
The answer is: B (34)
In order to get to the answer we must replace the value of x in each function f and g with (-3) and 3, respectively, and then subtract the functions.
(The exact mathematical steps are detailed in the answer section.)
