Question

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

0
1/3
1

Answer 1

The correct answer option is 1

Explanation:

We are given the following equation and we are to find the value of y when the point (-1, y) lies on the graph of the given equation:

`y = 3 ^ { x + 1 }`

So we will substitute the given value of x from the point (-1, y) in the equation to get y:

`y = 3^(-1+1)`

`y=3^0`

We know that anything with power zero is equal to 1.

Therefore, y = 1.

Answer 2

y=1

EXPLANATION

If (-1, y) lies on the graph of

`y = 3^(x+1)`

then it must satisfy its equation:

We substitute x=-1 in to the equation to get:

`y = 3^(-1+1)`

`y = 3^(0)`

Any non-zero number exponent 0 is 1.

This simplifies to:

y=1

Therefore when x=-1, y=1

The third choice is correct.
