Question

Find the following from the parabola below

2) axis of symmetry
3) vertex
4) domain
5) range
Use x=-b/2a to find the axis of symmetry and x-coordinate of vertex
Parabola: y=x^2-10x+5

Answer 1

Explanation:

Find the axis of symmetry of the graph of y=x2−6x+5 using the formula.

For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Here, a=1,b=−6 and c=5 .

Substitute.

x=−−62(1)

Simplify.

x=62 =3
