Answer:
y = 12 [tex](2.9)^{x}[/tex]
Step-by-step explanation:
The standard form of the exponential function is
y = a [tex](b)^{x}[/tex]
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so
a = 12, then
y = 12 [tex]b^{x}[/tex]
Using (1, 34.8 ) , then
34.8 = 12 [tex]b^{1}[/tex] ( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12 [tex](2.9)^{x}[/tex]
