If (-2, y) lies on the graph of y = 3^x, then what is y?

Solution:

Given, y = 3^x

The point (-2, y) lies on the graph of y = 3^x

We have to find y.

Put x = -2 in the above expression,

y = 3^-2

= 1/3²

= 1/9

Therefore, the value of y is 1/9.

If (-2, y) lies on the graph of y = 3^x, then what is y?

Summary:

If (-2, y) lies on the graph of y = 3^x, then the value of y is 1/9.
