Three functions are given below: f(x), g(x), and h(x).


B: What is the axis of symmetry for g(x)? Show the work steps.

g (x) = 5 x^2 - 10x + 7

Respuesta :

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

[tex]g(x)=5x^2-10x+7[/tex]

The degree of the equation is 2.  SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function [tex]f(x)=ax^2+bx+c[/tex] is a vertical line,

[tex]x=-\frac{b}{2a}[/tex]

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

[tex]x=-\frac{(-10)}{2(5)}[/tex]

[tex]x=\frac{10}{10}[/tex]

[tex]x=1[/tex]

Therefore, the axis of symmetry is x=1.
