Answer:

The value of y is 64.

Step-by-step explanation:

The given equation is

[tex]y=(\frac{1}{4})^x[/tex]

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,

[tex]y=(\frac{1}{4})^{-3}[/tex]

[tex]y=4^{3}[/tex]                      [tex](\frac{a}{b})^{-n}=(\frac{b}{a})^n[/tex]

[tex]y=64[/tex]

Therefore the value of y is 64.
