• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

The graph of which equation would translate the parent function up 2 and to the left 4?

• y = (x - 4)² + 2

•  y = (x + 4)² + 2

• y = (x + 4)² - 2

• y = (x - 4)² - 2

Look at function g.
g(x) = 9x² - 16
Which set contains only the zeros of function g?

• {-4/3, 4/3}

• {-4/3, 0, 4/3}

• {-16, 9}

Randy charges his tenants $400 each month to rent his houses plus $600 security deposit. In the new year, the property taxes increased on the area where he rents so as a result he must increase the rate of change by $25 to ensure his profits are not harmed. What equation best represents how much his tenants will now have to pay?

• y = 425x + 600

• y = 425 + 600x

• y = 400x + 625

• y = 400 + 625x

• y= 21.5x

The total cost (y) at an amusement park can be modeled by y=1.5x+20 where x is the number of rides you ride. What is the entrance fee?
