Identify the 'b' value: y = 16x² -8x -24

• 16

• -8

• 8

• -24

What is the y-intercept of this parabola?

• (−1, 3)
• (−3, 11)
• (−2, 5)
• (0, 5)

What is the y-intercept of: y=7x²+2x -1

• (0, 1)
• (0, -1)
• (1, 0)
• (-1, 0)

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

How many solutions does this graph have?

• one
• two
• no solutions
• cannot be determined
