Answer:
The answer is - 91
Step-by-step explanation:
f(x)=2x+1
g(x)=-5x+2
To find f(g(3)) first find f(g(x))
To find f(g(x)) multiply f(x) by g(x)
that's
f(g(x)) = (2x + 1)( - 5x + 2)
f(g(x)) = - 10x² + 4x - 5x + 2
f(g(x)) = - 10x² - x + 2
To find f(g(x)) when x = 3 substitute 3 into
f(g(x))
That's
f(g(3)) = -10(3)² - 3 + 2
f(g(3)) = -90 - 3 + 2
We have the final answer as
f(g(3)) = - 91
Hope this helps you
