Question

Cans of Soup 1 Number of Servings 4 2 8 3 12 4 16

Answer 1

`\begin{gathered} f(x)=4x \\ \text{where} \\ x=\text{Cans of soup} \\ f(x)=\text{Number of servings} \\ f(x)=4x \\ f(1)=4*1=4 \\ f(2)=4*2=8 \\ f(3)=4*3=12 \\ f(4)=4*4=16 \end{gathered}`

Where

x(cans of soup) = independent variable

Number of service(f(x)) = dependent variable
