Answer 1

The correct answer is option D which is f(x) is decreasing for all the values of x < 3.

What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The value of the function $f(x) = \dfrac{x+6}{x^2-9x+18}$ is represented on the graph in the graph we can see that at x>6 the value of the function is decreasing and at x<3 the value of the function is increasing.

Therefore the correct answer is option D which is f(x) is decreasing for all the values of x < 3.
