Find the x and y intercepts of f(x)=x^2x6.

y=f(x)=x^2x6
The yintercept is the value of y when x=0.
Substitute x=0 in the above equation to find the yintercept.
The xintercept is to find the roots of the equation, when y=0, or
f(x)=x^2x6=0
By factoring f(x) into
f(x)=(x3)(x+2)
you should be able readily find the two zeroes of f(x).
If you need further help, post again.

well i know the xintercept is (3,2)
but i can seem to understand y intercept. I thought it would be (0,0) but it was wrong

The yintercept is where the graph crosses the yaxis, that is, where x=0.
In this case, f(0) = 0  0  6 = 6, so the yintercept is (0,6)

Also, there are two xintercepts: (3,0) and (2,0). They are the points where the graph crosses the xaxis, not just the xvalues.
