Question

Let f(x)=x+3 and g(x)=1/2 the graph of (f•g)(x) is shown below

Answer 1

(1/2)x+3/2

or

0.5x+1.5

Explanation:

Hopefully you mean to have that dot between f and g closed because if it open it means something totally different.

So closed dot means multiplication

Open dot means you are composing a function with another one

So here you are just doing (x+3) * (1/2)

Just use distributive property (1/2)x+(1/2)(3)

(1/2)x +3/2

or

0.5x+1.5
