Question

Graph the functions by using substitution y=3* and y=-3* on the graph below. (Hint- Select 5 points: the y-intercept and two points on either side, sketch the function.)

Answer 1

`y=3^x`
`\begin{gathered} x\text y=3^x \\ ------------------- \\ -2\text (1)/(9)=0.11 \\ ------------------- \\ -1\text (1)/(3)=0.33 \\ ------------------- \\ 0\text \\ ------------------- \\ 1\text 3 \\ ------------------_{} \\ 2\text \end{gathered}`

The second table is

`\begin{gathered} x\text y=-3^x \\ ------------- \\ -2\text -(1)/(9)=-0.11 \\ ------------- \\ -1\text- (1)/(3)=-0.33 \\ -------------- \\ 0\text \\ -------------- \\ 1\text \\ --------------- \\ 2\text \end{gathered}`
