Y=3x+5

Step-by-step explanation:

If we take x = 1, according to the first function (the answer) y would be 8.

Other options:

—————

Formula 3:

Y= 2^x+5 == 7

Formula 4:

Y = x+8 == 9

True answer = 10.

——————

Ok, so the last one seems more accurate lets test the first and last one on two more numbers:

——————

X = 15

Formula 1:

50

Formula 4:

23

True answer = 60.

The first formula wins.

————————-

X= 10

Formula 1:

35

Formula 4:

18

True answer = 41

The first formula wins.

So, we can see that the first formula is most accurate.
