Question 135926
To find the x intercept, set y = 0 and solve for x.

To find the y intercept, set x = 0 and solve for y.

SAMPLE:

Find the x and y intercepts of the function 3x^2 - y = 6

You can find either intercept first.

x intercept:

Replace y with 0 and solve for x.

3x^2 - (0) = 6

3x^2 = 6

Divide both sides by 3.

x^2 = 6/3

x^2 = 2

Take square root of both sides.

x = +sqrt{2}, -sqrt{2}....Here are the two x intercepts.

=======================================================

y intercept:

Replace x with 0 and solve for y.

3x^2 - y = 6

3(0)^2 - y = 6

0 - y = 6

-y = 6

Divide both sides by -1.

y = 6/-1

y = -6...This is your y intercept.

Is this clear?
