Question

I need help on this question anyone know this ?

Answer 1

y = 4
`(2)^(x)`

Explanation:

An exponential function in standard form is

y = a
`b^(x)`

Use ordered pairs from the table to find a and b

Using (0, 4), then

4 = a
`b^(0)` ( note that
`b^(0)` = 1 ), so

a = 4, then

y = 4
`b^(x)`

Using (1, 8)

8 = 4
`b^(1)` = 4b ( divide both sides by 4 )

b = 2

y = 4
`(2)^(x)` ← represents the values in the table
