Write the equation of the quadratic function that has a x-intercepts at (2, 0) and (4, 0) and passes through the point (3, 4) in factored form. Do not use spaces! y=

Answer explanation

Use the x-intercepts to write the two factors, remember you have to use the OPPOSITE sign!

Then substitute in the other point for x and y, then go forward in solving for a. Remember, the side with the factors is all multiplication! You are only adding/subtracting inside the parentheses, then multiplying those together, and those times a. That means your last step is division.

Write a quadratic function with roots of -7 and -3.

• y = (x+7)(x+3)

• y = (x-7)(x+3)

• y = (x+7)(x-3)

• y = (x-7)(x-3)

Write a quadratic function with roots of 11 and 29.

• y = (x+11)(x+29)

• y = (x+11)(x-29)

• y = (x-11)(x+29)

• y = (x-11)(x-29)

Write the equation of the quadratic if it goes through (-1, 2) and has the given intercepts.

• y=5/2 (x-0)(x-4)

• y = 2/5 (x-0)(x-4)

• y= 2/3 (x-0)(x-4)
