Question

If (-2, y) lies on the graph of y = 4x, then y =

-16
1/16
16

Answer 1

Explanation:

(-2, y) lies on the graph of
`y = 4^x`

It means for x=-2 we need to find the y =?

means we plug x=-2 in the given equation
`y = 4 ^x`

so we get

`y = 4^ (-2)`

`y = (1)/(4^2)`

`y = (1)/(16)`

Answer 2

y = 4x
(-2,y).....x = -2

y = 4(-2)
y = -8
