Answer:
y = x + 3
y = 3x²
y = [tex]3^{x}[/tex]
Step-by-step explanation:
Relationship1
y = x + 3
y = (0) + 3 = 3
y = (1) + 3 = 4
y = (2) + 3 = 5
Relationship 2
y = 3x²
y = 3(0)² = 0
y = 3(1)² = 3
y = 3(2)² = 3(4) = 12
Relationship 3
y = [tex]3^{x}[/tex]
y = [tex]3^{0}=1[/tex]
y = [tex]3^{1}=3[/tex]
y = [tex]3^{2}=9[/tex]
