Question

Based on the graph of y = x2 − 2x − 3, what is the x coordinate of the positive x-intercept

Answer 1

Put y = 0 here..

and find x first..

Answer 2

\[x^2 - 2x - 3 = 0\]

Factorize this..

Answer 3

(x + 1)(x - 3)

x + 1 = 0 / x = -1
X - 3 =0 / x + 3 ???

Answer 4

x =3

Answer 5

So what is positive one?/

-1 or 3 ??

Answer 6

3!

Answer 7

So positive is 3

So this will be x intercept that is positive..

Answer 8

And this will be the x coordinate of positive x intercept..

Answer 9

ok thanks you :))
