If (-1, y) lies on the graph of y = 22^x, then y =

Solution:

Given, the point (-1, y) lies on the graph of y = 22ˣ.

We have to find the value of y.

Now, y = 22ˣ ---------------------- (1)

Put x = -1 in (1)

y = 22⁻¹

Using the law of exponents,

a⁻ⁿ = 1/aⁿ

So, 22⁻¹ = 1/22

Therefore, y = 1/22

If (-1, y) lies on the graph of y = 22^x, then y =

Summary:

If (-1, y) lies on the graph of y = 22^x, then y = 1/22.
