Romashka-Z-Leto [24]

Answer:

Axis of symmetry is

C) x = 1

Step-by-step explanation:

we are given equation as

$2x^2 -4x+5$

we can use axis of symmetry formula

Let's assume we are given quadratic equation as

$y=ax^2+bx+c$

Axis of symmetry is

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

now, we can compare both equations

and we get

$a=2,b=-4$

now, we can find axis of symmetry

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

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

$x=1$
