Answer:
y = [tex]3^{x}[/tex]
Step-by-step explanation:
the standard form of an exponential function is
y = a[tex]b^{x}[/tex]
Use ordered pairs from the table to find a and b
Using (0, 1 ) , then
1 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , so
1 = a × 1 , that is a = 1
y = [tex]b^{x}[/tex]
Using (1, 3 )
3 = [tex]b^{1}[/tex] ⇒ b = 3
y = [tex]3^{x}[/tex] ← required exponential function
