Question

What’s the equation

Answer 1

y = 4.
`3^(x)`

Explanation:

For an exponential function in the form

y = a
`b^(x)`

Use ordered pairs from the table to find a and b

Using (0, 4 ), then

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

a = 4

y = 4
`b^(x)`

Using (1, 12 ), then

12 = 4
`b^(1)` = 4b ( divide both sides by 4 )

b = 3

Thus

y = 4 .
`3^(x)` ← exponential equation
