Micaela's Dad pays her $50.00 a month to drive her brother to practice plus $5.00 for ever game she drives to. The equation y = 50 + 5x can be use to represent this with x being the number of games driven to. What is a reasonable range if no more than 8 games are played?

• $0\le y\le8$

• $50\le x\le90$

• {0, 1, 2, 3, 4, 5, 6, 7, 8}

• {50, 55, 60, 65, 70, 75, 80, 85, 90}

What is the domain of the function graphed on the grid?

• {-1}

• $-5\le x\le5$
