Question

How do I use the graph to evaluate the expression

Answer 1

`(g\circ f)(-2)=1.5`

Explanation:

We have that:

`(g\circ f)(-2)=g(f(-2))`

Which means that we first have to find f(-2), and the evaluate the result in g.

Let's take a look at the plot of f(x) to find f(-2):

This way, we can conlcude that:

`f(-2)=-3`

Now, let's take a look at the plot of g(x) to find g(-3):

This way, we can conclude that:

`g(-3)=1.5`

Therefore, we can conclude that:

`(g\circ f)(-2)=1.5`
