Question

If the function rule is y = x/2 + 3 and x = 8, what is the value of y?

A. y = 1
B. y = 4
C. y = 7
D. y = 13

Answer 1

The correct answer is c, y =7. I got my answer by first plugging in 8 for x:

y = 8/2 + 3

Next, I divided 8 by 2 and got 4.

y = 4 + 3

Lastly, I added 4 + 3 to get 7.

So your final answer in y = 7.
