Question

What is the axis of symmetry for f(x) = 2x2 − 4x + 5?

Answer 1

Answer:

C. x = 1

Step-by-step explanation:

The axis of symmetry is found by the equation: -b/2a.

We are given f(x) = 2x^2 - 4x + 5, where:

• a = 2
• b = -4

Substitute these values into the formula for a.o.s.

-(-4)/2(2) --> 4/4 = 1

The a.o.s. is x = 1.

Answer 2

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

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

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

$x=1$
