Answer 1

To find intercepts, simply set a variable equal to 0. In this case, we want x-intercepts, so the y-value at any point on the x-axis is 0.

y = x^2 - 2x - 3
0 = x^2 - 2x - 3

Now we factor:
0 = (x-3)(x+1)

Set each term equal to 0 separately:
x-3 = 0 --> x = 3
x+1= 0 --> x = -1

So the answer is 3.
