Select the correct answer. Consider the function f(x)=x^2-3x/x^2-9. Which graph is the graph of function f?

Respuesta :

Simplifying the function, it's graph is given at the end of this answer.

The function is:

[tex]f(x) = \frac{x^2 - 3x}{x^2 - 9}[/tex]

The numerator can be factored as:

[tex]x^2 - 3x = x(x - 3)[/tex]

Using subtraction of perfect squares, the denominator can be factored as:

[tex]x^2 - 9 = (x + 3)(x - 3)[/tex]

Hence, the simplified function is:

[tex]f(x) = \frac{x^2 - 3x}{x^2 - 9} = \frac{x(x - 3)}{(x + 3)(x - 3)} = \frac{x}{x + 3}[/tex]

Using a calculator, the graph is sketched at the end of this answer.
