What is the axis of symmetry for f(x) = 2x2 - 8x + 8?<br> Ox<br> = -2<br> Ox=-3<br> Ox=3<br> Ox=2
zepelin [54]

Answer:

  x = 2

Step-by-step explanation:

For quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a).

Here, we have a=2, b=-8, so the axis of symmetry is ...

  x = -b/(2a) = -(-8)/(2(2)) = 8/4

  x = 2

Example 2
Arada [10]

Answer:

y=x-2

Step-by-step explanation:

If you have drawn the graph of y = x^2 - 3x + 1.

To determine the equation of the line which  should be drawn to solve the equation:  x² - 4x +3=0

Simply carry out the subtraction: x^2 - 3x + 1 -(x^2 - 4x +3)

\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3  + 1\\=x-2

The equation of the line which should be drawn is: y=x-2

What this means is simply:

If

y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0
