Answer:
y = 4[tex](2)^{x}[/tex]
Step-by-step explanation:
An exponential function in standard form is
y = a [tex]b^{x}[/tex]
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a [tex]b^{0}[/tex] ( note that [tex]b^{0}[/tex] = 1 ), so
a = 4, then
y = 4 [tex]b^{x}[/tex]
Using (1, 8)
8 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = 2
y = 4 [tex](2)^{x}[/tex] ← represents the values in the table
