Graphing Quadratic Equations #1

What is the vertex?

f(x) = 1/2(x + 5)² + 8

• (-5, -8)

• (5,-8)

• (5, 8)

• (-5, 8)

True or false:
The root, x-intercept, and zero 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
