Answer:
D. exponential function
As the x-values are increased by a constant amount, the y-values are multiplied by a constant amount.
Explanation:
From the table of values:
x-values
[tex]\begin{gathered} 0-(-2)=2 \\ 2-0=2 \\ 4-2=2 \end{gathered}[/tex]The x-values increase by a constant amount, 2.
y-values
[tex]\begin{gathered} \frac{12}{4}=3 \\ \frac{36}{12}=3 \\ \frac{108}{36}=3 \end{gathered}[/tex]The y-values are multiplied by a constant amount, 3.
As the x-values are increased by a constant amount, the y-values are multiplied by a constant amount.
The correct option is D.
