let f(x)=5x-1and g(x)=x^2-4
Find (fog)(2)=
Simplify
To find (fog)(2), we need to first find g(2) and then plug that value into f(x).
Step 1: Find g(2)
g(x) = x^2 - 4
g(2) = 2^2 - 4
g(2) = 4 - 4
g(2) = 0
Step 2: Plug g(2) into f(x)
f(x) = 5x - 1
f(g(2)) = 5(0) - 1
f(g(2)) = 0 - 1
f(g(2)) = -1
Therefore, (fog)(2) = -1.
