Suppose that the functions p and g are defined as follows.
P (x) = 2x
Q (x) = - 2x^2 - 2
Find the following.
(q•p)（3）=
First, we need to find the value of q•p, which means Q(x) * P(x).
P(x) = 2x
Q(x) = -2x^2 - 2
(q•p)(x) = (Q(x)) * (P(x))
= (-2x^2 - 2) * (2x)
= -4x^3 - 4x
Now, we need to find (q•p)(3) by plugging in x = 3.
(q•p)(3) = -4(3)^3 - 4(3)
= -4(27) - 12
= -108 - 12
= -120
Therefore, (q•p)(3) = -120.
