What direction is the following equation opening?
y=-3x²-7x+8

• Concave Up
• Concave Down

How do you know if a parabola has a minimum vertex?

• When "a" is positive there is a minimum
• When "a" is negative there is a minimum
• When all the numbers in the equation are negative there is a minimum
• When all the numbers in the equation are positive there is a minimum

Use the graph to determine the
x-intercepts.

• (-1,0) and (-3,0)
• (0,1) and (0,-3)
• (1,0) and (3,0)
• (-1,0) and (3,0)
