A triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral

Explain how to determine which numbers must be excluded from the domain of a rational expression. Please provide an example with

Katarina [22]

Answer:

When we are having a rational expression i.e. a expression of the type:

$\dfrac{f(x)}{g(x)}$

Where f(x) and g(x) are polynomial functions.

Now the domain of this rational expression is whole of the real numbers except the points where the function g(x) will be zero.

Hence we have to exclude the points where the given denominator quantity is zero.

Let us consider an example as:

Let R(x) denote the rational function as:

$R(x)=\dfrac{x^2}{(x-2)(x-3)}$

Now the domain of this rational function will be whole of the real line minus the points where the denominator is zero.

We know that (x-2)(x-3) is zero when x=2 or x=3.

Hence, the domain of R(x) is: R- {2,3}.
