4/12 Review HW/CW

What are the green dots called?

• axis of symmetry
• vertex
• parabola
• roots or x-intercepts

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 is the greatest number of solutions that a Quadratic Equation can have?

• 0
• 1
• 2
• 3

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.

Solutions to quadratic equations are the points where the functions intersects the y-axis.

• true

• false

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
