How do you find points of intersection?

Answer 1

You could use a graphing calculator..

or..

if you have 2 functions...

get y (or x) on one side like: y = blah blah blah

then get the other equation to do that too.

Now you have two equations that equal to y.

so now you get y = equation A, and y = equation B and put them together.

Like so:

equation A = equation B

Now you solve for x, I'll assume you know how.

If there are absolute values, you'll have to do more work though.

Now you found the points of intersection!
