Question

If (-3, y) lies on the graph of y = y= ( 1/4)x; then y =

Answer 1

The ordered pair (-3,64) lies on the graph

The value of y=64

Explanation:

we know that

If a ordered pair lies on the graph of y

then

the ordered pair must satisfy the equation of y

In this problem we have

`y=((1)/(4))^(x)`

For x=-3

substitute the value of x in the exponential equation

`y=((1)/(4))^(-3)=4^3=64`

therefore

The ordered pair (-3,64) lies on the graph

The value of y=64
