Answer: 2
Step-by-step explanation:
We put the g(x) in the f(x) function, we get f(x) = 2x + 1 -3. We simplified it, so we get f(x) = 2x - 2.
And we plug in 2 for x to solve for f(2).
f(x) = 2x - 2
f(2) = 2(2) - 2
f(2) = 4 - 2
f(2) = 2
Answer: The placebo group serves as the control group because this group corresponds to the reference point that will be compared to the other group.
