Answer:
C
Step-by-step explanation:
We want to find the value of <em>x </em>such that:
Recall that this is equivalent to:
Note that the outside function is m(x) and the inside function is n(x).
So, for the function to equate to 2, our input must allow the outside function to equal 2.
From the graph, we can see that m(1)=2.
Therefore n(x) must be 1.
And using the table, we can see that n(-3)=1.
So, the value of <em>x</em> is -3.
Checking, we see that:
Our answer is C.
