Answer:

y = 4(2)^{x}

Step-by-step explanation:

An exponential function in standard form is

y = ab^{x}

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = ab^{0} [ b^{0} = 1 ], so

a = 4

y = 4b^{x}

Using (1, 8 ), then

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

b = 2

y = 4 (2)^{x} ← exponential equation
