Question

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

Answer 1

Answer:

The value of y is 64.

Step-by-step explanation:

The given equation is

$y=(\frac{1}{4})^x$

It is given that (-3, y) lies on the graph of y. It means the equation of the function must be satisfy by the point (-3,y).

Substitute x=-3 in the given equation to find the value of y,

$y=(\frac{1}{4})^{-3}$

$y=4^{3}$                      $(\frac{a}{b})^{-n}=(\frac{b}{a})^n$

$y=64$

Therefore the value of y is 64.
