Question

how to find the range of square root fuctions

Answer 1

what restrictions are there on square roots?

Answer 2

For this function there are only positive y-values. There is no value of x that we can find such that we will get a negative value of y. We say that the range for this function is y ≥ 0

Answer 3

\[f(x)=\sqrt{2x+3}\]

Answer 4

what ever inside square root is put like this :
elemnt of square root >=0
now u may solve the above equation u will get the domain
and for range the only way to know the range is to graph the problem then u can find the range through the greaph
