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.)

Sagot :

[tex]y=3^x[/tex][tex]\begin{gathered} x\text{ | }y=3^x \\ ------------------- \\ -2\text{ | }\frac{1}{9}=0.11 \\ ------------------- \\ -1\text{ | }\frac{1}{3}=0.33 \\ ------------------- \\ 0\text{ | 1} \\ ------------------- \\ 1\text{ | 3} \\ ------------------_{} \\ 2\text{ | 9} \end{gathered}[/tex]

The second table is

[tex]\begin{gathered} x\text{ | }y=-3^x \\ ------------- \\ -2\text{ | -}\frac{1}{9}=-0.11 \\ ------------- \\ -1\text{ |- }\frac{1}{3}=-0.33 \\ -------------- \\ 0\text{ | -1} \\ -------------- \\ 1\text{ | -3} \\ --------------- \\ 2\text{ | -9} \end{gathered}[/tex]
