Question

If (-1, y) lies on the graph of y = 3^x+1, then y =

Answer 1

Answer:

y = 4/3

Step-by-step explanation:

y = 3^x+1

Substitute -1 for x.

y = 3^(-1)+1

y = 1/3 + 1

y = 1/3 + 3/3

y = 4/3

Answer 2

Answer:

If this was your equation $y=3^x+1$ then the answer is 4/3.

If this was your equation $y=3^{x+1}$ then the answer is 1.

Step-by-step explanation:

It is basically asking us to replace x with -1 and find y.

If $y=3^x+1$ and we plug in -1 for x, we get $y=3^x+1=3^{-1}+1=\frac{1}{3}+1=\frac{4}{3}$ .

If $y=3^{x+1}$ and we plug in -1 for x, we get $y=3^{x+1}=3^{-1+1}=3^0=1$.
