Question

Just part b please. I can’t find the values to plug into the equation

Answer 1

The given composite function is:

`\begin{gathered} (g\circ f)(x)=7 \\ \text{Which means} \\ g(f(x))=7 \end{gathered}`

As we can see in the table, g(x)=7 when x=2, in this case the argument of g(x) is f(x), then f(x)=2. Again, in the table we find that f(x)=2 when x=1, then:

`g(f(1))=g(2)=7`

Then the solution is x=1:

`(g\circ f)(1)=7`
