OLga [1]4 years ago

Answer:

y = 4. 3^{x}

Step-by-step explanation:

For an exponential function in the form

y = ab^{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
