Question

The graph of the function f(x)= x2 − 4x + 6 is shown here. What is its axis of symmetry?

Answer 1

Answer:

Axis of symmetry at $x=2$

Step-by-step explanation:

The graph of the function $f(x)= x^2 - 4x + 6$

To find axis of symmetry we use formula $x=\frac{-b}{2a}$

Given equation is in the form of

$y=ax^2+bx+c$

$a=1, b=-4, c=6$

Plug in the values in the formula

$x=\frac{-b}{2a}$

$x=\frac{-(-4)}{2(1)}$

$x=2$

Axis of symmetry at $x=2$

Answer 2

X=-b/2a

x = 4/2=2
