How to find the y-intercept of a factored quadratic equation

[abel muroi]

Lets say i was given the problem...


P(x) = 1/12 (x + 2)² (x - 3)²


I know this is already factored but my question is...

In order to find the y - intercept of this equation, do i have to multiply -3, 2 and 1/12 to get the y-intercept? or is there other ways to get the y-intercept?

if thats true then the y-intercept is 3

Not quite. What does y-intercept mean?

I was asked to graph the equation, and in order for me to do that.. i need to find the roots of the equation in factored form. (roots = x- intercepts)

but i also need the y-intercept so that i can graph this quadratic equation.

Do you know what a quadratic equation is?
You better have a talk with your teacher.

I meant polynomials, im trying to graph polynomials

The y intercept is the place where the graph crosses the y axis. What is the value of x on the y-axis. Substitute that value into the function to get the y-intercept.

I am more concerned that you can't multiply those three numbers correctly!
What does every point on the y-axis have in common?
