Use f(x)=5x+2 and g(x)=3-x. what is the value of f(g(-1)) and g(f(-1))?
1 answer:
Answer:
f(g(-1)) = 22
g(f(-1))=6
Step-by-step explanation:
We are given
We need to find f(g(-1)) and g(f(-1))
Finding f(g(-1))
First we will find f(g(x)) i.e
Now finding f(g(-1)) by putting x=-1
So, f(g(-1)) = 22
Finding g(f(-1))
First we will find g(f(x)) i.e
Now finding g(f(-1)) by putting x=-1
So, g(f(-1))=6
