for the function f(x) = 3x + 4 and g(x) = x^2 - 2 Gina (f•g)(-2)
To find the value of (f•g)(-2), we first need to calculate f(-2) and g(-2) using the given functions f(x) and g(x).
1. Let's start with f(x):
f(x) = 3x + 4
f(-2) = 3(-2) + 4
f(-2) = -6 + 4
f(-2) = -2
2. Now, let's calculate g(x):
g(x) = x^2 - 2
g(-2) = (-2)^2 - 2
g(-2) = 4 - 2
g(-2) = 2
Now that we have both f(-2) and g(-2), we can find (f•g)(-2) by multiplying the two values:
(f•g)(-2) = f(-2) * g(-2)
(f•g)(-2) = (-2) * 2
(f•g)(-2) = -4
Therefore, (f•g)(-2) = -4.
