Alright, so we need to find the x and y intercepts of this function.
00:07
So the intercepts are where the x intercept is where y is equal to zero.
00:16
This is where the line touches the x -axis.
00:20
So i know that the x -intercept should be whatever the x -cordinate is, and i know that y has to be zero.
00:29
Then for the y intercept, the opposite is true.
00:36
I know that x has to be zero because this is where the line touches the y axis.
00:43
So y has to be zero and then x, or sorry, x has to be zero, and then y is just whatever that y coordinate is, wherever it touches the y axis.
00:56
So the reason that that helps is because i know that for my x intercept, y has to be 0.
01:04
So i can just plug 0 in for y into my function.
01:08
So if i do that, i get x plus 0 instead of y is equal to 4.
01:16
So i just need to solve this equation for x, and that'll tell me what my x intercept is...
