Question 240669
---
g(x)=x^2+3x
 
h(x)=(x+3)/2
 
find (h*g)(-1)
============================
Multiply the two algebraic expressions; then evaluate that product at x=-1.
--------------------------------------------
(h*g)(-1) = [(x+3)/2]*[x^2+3x](-1)
---
[(x^3+3x^2)/2](-1)
---
[(-1)^3+3(-1)^2]/2
---
=[-1+3]/2
=[2/2]
= 1
