Which is the graph of f(x)=x^2-2x+3

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Hello, the vertex is (1,2), right?

You remember that when the parabola equation is in standard form like below

$y=ax^2+bx+c$

The vertex is for , and we apply with this example where a = 1, b = -2, c=3

$x=-\dfrac{b}{2a}=\dfrac{-(-2)}{2}=1\\\\1^2-2*1+3=4-2=2$

So this is the first graph.

Thank you
