Use the vertical line test to answer this.  Draw a vertical line thru the graph at any x value for which there is a graph.  If the vertical line crosses the graph exactly once, you've got yourself a function; otherwise, you don't.

square that and slap it under the y²
Put that all after the "+"

8 A video game that usually costs $50 is on sale for $32.50
finlep [7]

The video game is on 35% discount.

Step-by-step explanation:

Cost of video game = $50

Price on sale = $32.50

Amount of discount = Original price - price on sale

Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5

Percentage = \frac{Dicount\ Price}{Original\ Price}*100

Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%

The video game is on 35% discount.
