The net area and range calculator with steps reveals domain and variety for a feature in multiple clicks. Examines the range wherein the area of a certain mathematical characteristic exists. not handiest this, but you will also get results in right set c program languageperiod notations.
precise set of values that help to outline a feature after they are installed it through our area calculator.
The set of values that the feature yields after the domain values are installed it.
Go through the example underneath to higher apprehend the way to find the area of a feature along side its variety!
Statement:
Find the domain and range of the graph function given as under:
$$ y=\dfrac{2x+5}{12-x} $$
Solution:
Domain:
First, search for the fee of x to be able to make the denominator zero. In our case, it's far 12, such that;
$$ 12-x = 12-12 = 0 $$
So 12 is the range that undefines the whole expression. that is why it is not covered within the domain.
Range:
Solving for x:
$$ y=\dfrac{2x+5}{12-x} $$
$$ y\left(12-x\right)=2x+5 $$
$$ 12y-xy=2x+5 $$
$$ -xy-2x=5-12y $$
$$ -x\left(y+2\right) $$
$$ -x=\dfrac{5-12y}{\left(y+2\right)} $$
$$ x=\dfrac{12y-5}{-\left(y+2\right)} $$
Now if you put the value of y as -2, it will again make the denominator zero such that:
$$ x=\dfrac{12y-5}{-\left(\left(-2\right)+2\right)} $$
