Answer:

y = 4[tex](2)^{x}[/tex]

Step-by-step explanation:

An exponential function in standard form is

y = a[tex]b^{x}[/tex]

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

Using (0, 4 ), then

4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so

a = 4

y = 4[tex]b^{x}[/tex]

Using (1, 8 ), then

8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )

b = 2

y = 4 [tex](2)^{x}[/tex] ← exponential equation
