Question

Find the x-intercepts of the graph

Answer 1

Answer:

(1,0) and (3,0)

Step-by-step explanation:

y=x^2-4x+3

To factor we need to know what numbers add up to -4 and multiply will equal to 3.

y=(x-3)(x-1)

The zeroes would be 3 and 1.

x=3  so y=0 for (x-3)

x=1 so y=0 for (x-1)

If right pls give me brainliest thank you.

Answer 2

Answer:

(1, 0) and (3, 0)

Step-by-step explanation:

$y=x^2-4x+3$

Plug y as 0 to find the x-intercepts.

$0=x^2-4x+3$

Factor right side.

$0=x^2-1x-3x+3$

$0=x(x-1)-3(x-1)$

$0=(x-1)(x-3)$

Set factors equal to 0.

$x-1=0\\x=1\\x-3=0\\x=3$

x=1 or x=3 when y=0
