Quadratic Functions: Graphs & Equations

Use the graph to determine the solutions in factored form.

*you can use Desmos for any of these questions if you need!!

• (x+1)(x+3)

• (x+1)(x-4)

• (x-1)(x-3)

• (x-1)(x+3)

Use the graph to determine the factored form of the quadratic function

• y=(x-2)(x+1)

• y=(x-5)(x-1)

• y=(x+1)(x-5)

• y=(x+1)(x+5)

The solutions of the quadratic function pictured are:

• {-3,-7}

• {3,7}

• {-5,3}

Use the graph to determine the factored form of the quadratic function

• y = (x+4)(x+7)

• y = (x+5)(x+3)

• y = (x-7)(x-3)

• y = (x + 7)(x + 3)

The solutions of the quadratic function pictured are:

• {-1, 3}

• {1, 3}

• {-3, 1}

Based on your solutions to this graph (x-intercepts), what is your equation in factored form?

• y=(x-1)(x+3)

• y=(x+1)(x+3)

• y=(x+1)(x-3)

What are the
x-intercepts of the function
f(x)= (x - 2)(x + 3)?

• x = - 2 or x = 3
• x = 2 or x = -3
• The are no real roots
• x = 2 or x = 3
