I believe the answer is b.
The solution to these linear equations is (4,-3)
So the x-value is 4

Answer: OPTION C
Given the functions shown in the figure attached, you have that f(x)*g(x), means that you must multiply both functions.
Therefore, you have:

Now, you must apply the distributive property, therefore, you obtain:

As you can see, the answer is the Option C.
