Question

Jamie has 3 game tickets more than twice her brother'sgame tickets. The function rule, 3x + 2 where x is herbrother's tickets, can be used to find Jamie's numberof tickets. Make a table of values that show how manytickets Jamie has when her brother has 40, 50, and60 tickets. Then graph the function.

Answer 1

To find the number of tickets Jamie has, we can insert the value of x into the function

`y=3x+2`
`\begin{gathered} x=40 \\ y=3(40)+2 \\ y=120+2 \\ y=122 \end{gathered}`
`\begin{gathered} x=50 \\ y=3(50)+2 \\ y=150+2 \\ y=152 \end{gathered}`
`\begin{gathered} x=60 \\ y=3(60)+2 \\ y=180+2 \\ y=182 \end{gathered}`

the graph of the function is
