Solving Quadratics Review

What  are the solutions of this graph?

• -2 and 3

• -1/2 and -6

• -2 and -6

• 3 and -6

What are the solutions?

• 0 and 8

• -2 and -4

• 3 and -1

• 2 and 4

What is another word that describes the zeroes of a quadratic function?  

• y-intercepts

• vertex

• x-intercepts

• maximum

If the graph of a quadratic does not intercept the x-axis at any point, then it has:

• 1 Real Solution

• 2 Real Solutions

• Half a Solution

• No Real Solution

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

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
