Find the range of a function by substituting the highest domain possible and the lowest domain possible into the function. There, you will find the highest and lowest range.
Then, you should check all the possible cases in the function where a number could be divided by 0 or a negative number could be square rooted. Remove these numbers from the range.
A good way to check to see if you have the correct range is to graph the function (within the domain, of course).

What are common terms to represent domain and range and how do you find them?
x = the domain y = the co-domain and range is the output or something e_e
How do you find the domain and range of a parabola?
The domain is any subset of the real numbers that you choose, The range is the set of all values that the points in the domain are mapped to.
Find the domain and range of the equation 3x - 2y equals 6?
domain is set of real numbers range is set of real numbers
How do you find the domain and range of f of x equals x squared minus 3x minus 10?
The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).
How you would find the domain and range of a function when given its graph?
To find the Domain and range when given a graph is to take the x-endpoints and to y-endpoint. You know that Domain is your input and range your output. so to find the function when given the graph you simply look at your plot points and use yout domain and range. like so: Say these where your plot points (0,4) and (9,6) You know your domain is {0,9} and it would be written like so: 0<x<9 then noticing your range is {4,6} and it would be written like so: 4<y<6
