MULTIPLE CHOICE QUESTION

1 min • 1 pt

Media Image

Write a quadratic equation given the x intercepts and one other point.

Step 3: Write the equation in factored form.

Now, you know that the factors are (x-6) and (x-8) and a = -1. Write the equation of the graph in factored form.

(x-6)(x-8)

(x+6)(x+8)

(x-6)(x+8)

(x+6)(x-8)

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Write the equation of the quadratic function that has a x-intercepts at 2 and 4 and passes through the point (3, 4).

y = -4(x - 2)(x - 4)

y = -4(x + 2)(x + 4)

y = 4(x - 2)(x - 4)

y = -0.25(x - 2)(x - 4)

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Write the equation of the quadratic function that has a x-intercepts at 9 and 1 and passes through the point (0, -18).

y = x2 + 9x - 18

y = -2(x - 9)(x - 1)

y = -2(x + 9)(x + 1)

y = 2(x + 9)(x + 1)

This is what form? y = 5(x+2)(x-1)

Standard

Vertex

Factored

None of These

Media Image

Write the equation of the quadratic function in intercept form (factored).

y = (x + 1)(x - 1)

y = x2 + 1

y = ( x - 1 )2

y = ( x + 1 )2

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Media Image

Which equation represents this graph.

f(x)=(x - 4)2 - 3

f(x)=-(x - 4)2 + 3

f(x)=(x - 4)2 + 3

f(x)=-(x + 4)2 + 3

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Media Image

Write a quadratic equation given the x intercepts and one other point.

Step 2: Find a.

Now that you know that the factors are (x-6) and (x-8), you must find a. Plug the coordinates of the vertex (7, 1) in for x and y and solve for a.

y = a(x-6)(x-8)


What is the value of a?

a = 1

a = -1

a = 7

a = -7
