Suppose that the functions p and g are defined as follows.
P (x) = 2x
Q (x) = - 2x^2 - 2
Find the following.
(p•q)（3）=
To find (p•q)(3), we first need to evaluate p(3) and q(3), and then multiply the two results.
p(3) = 2(3) = 6
q(3) = -2(3)^2 - 2 = -2(9) - 2 = -18 - 2 = -20
Now we multiply p(3) and q(3):
(p•q)(3) = p(3) • q(3) = 6 • -20 = -120
Therefore, (p•q)(3) = -120.
