Answer:
-1
Step-by-step explanation:
get -3 to the other side of the equation. 2a=-2 so a is -1
Do this by finding g(5) first. Replacing x with 5 in g(x) gives you that g(5) = 3. Now replace that 3 in the x in f(x) to get that f(3) = 3. As far as the domain goes,, they are both lines and the domain for lines is all real numbers.
