Quadratic Formula Introduction

Determine the vertex of y = 4x² +5

• (4,5)
• (4,-5)
• (0,5)
• (0,-5)

Determine if the vertex is a maximum or minimum:
y = 3x² - 4

• max
• min
• none of these

Determine the vertex of y = x²

• (1,1)
• (1,0)
• (0,1)
• (0,0)

Which of the following is used to find the discriminant?

• aX²  + bX  +  c
• b - 4ac
• b² - 4ac
• b² + 4ac

If the discriminant is 0 you will have:

• no real solutions
• two real solutions
• 1 real solution
• 1 imaginary solution

If the discriminant is a positive number, then you will have

• one real solution
• two real solutions
• no real solutions
• one imaginary solution

If the discriminant is a negative number, then you will have

• one real solution
• two real solutions
• no solution
• infinite solutions

Find the discriminant
3x² -x- 2 = 0

• 5
• 25
• -24
• -26

Find the vertex of the quadratic:
y = -2x² + 4x + 3

• (0, 3)
• (-1, 5)
• (1, 5)
• (1, -5)

Does this parabola have a maximum or minimum?

• Maximum
• Minimum
