## anonymous 4 years ago whats domain and range

domain is what you can use; range is what you can get

THE DOMAIN IS X AND THE RANGE IS Y

to expand on what amistre said - if you have an equation of the form:$y=f(x)$ the domain is what values of x can be used in f(x). the range if the range of values that this generates for y - i.e. minimum y to maximum y. as an example, for this function:$y=\frac{x}{x−1}$the domain cannot include the value x=1 as that would not give you a value value for y. so the domain here is $$x\ne1$$.

the range in the above example would be $$(-\infty, +\infty)$$

it is making any sense to you?
