Question

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

1/27
-1
-27

Answer 1

Answer:

y =1/27

Step-by-step explanation:

Howdy!

If P = (-3, y) lies on the graph of y=3^x, then, to find the value of 'y' we need to substitute the point P into the equation:

To solve this, remember that $a^{-b} = \frac{1}{a^{b}}$

Then:

y = 3^x

y = 3^(-3)

y = 1/27

So P= (-3, 1/27)

The correct option is y =1/27

Answer 2

Answer:

The correct answer option is 1/27.

Step-by-step explanation:

We are given the following equation and we are to find the value of y when the point (-3, y) lies on the graph of the given equation:

$y = 3 ^ { x }$

So we will substitute the given value of x from the point (-3, y) in the equation to get y:

$y = 3 ^ { - 3 }$

$y = \frac { 1 } { 2 7 }$
