Quads - graph, factor, square root

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

Write a quadratic function in intercept form.

y = a(x - r1)(x - r2)

Determine the domain and range of the function

• Domain: All real numbers, Range: All real numbers

• Domain: x ≥ -4, Range: All real numbers

• Domain: All real numbers, Range: y ≥ -4

• Domain: -1 ≤ x ≤ 5, Range: y ≥ -4

What is the vertex of y = x² + 4x + 3?

• (2,1)

• (-2,1)

• (0,0)

• (-2,-1)

What are other names for the solutions to quadratic equations?

Select ALL that apply.

• x-intercepts

• y-intercepts

• roots

• zeros

Factor and Solve: Remember the two numbers you choose when factoring, are not your solutions to the equation!

a² + 2a − 24 = 0

• a = −6 and a = 4

• a = 6 and a = −4

• a = 12 and a = −2

• a = 8 and a = −3

find x for
2x²-8x-24=0

• x= 6, -2
• x= 2, -6
• x= 4, 2
• x= 2, 6
