Well, It's been a while since I was in Calc, but basicly for the domain, what values of X would make the equation invalid. Since 4-x is under the root/ratical, then 4-x must be greater than 0 or else you end up with an imaginary answer and that's not good. So pretty much, you just have to solve the equation 4-x ( > or equal to) 0. When you solve that you'll get 4 (> or equal to) x. So you end up with a domain of
Dx= (-Infinity , 4]. which basicly says that all values from negative infinity to 4 work as a value of x and is the domain
As far as range is concerned, i don't remember how to find it the technical way, but basicly, for a negative root problem, the range is always
Ry= (-Infinity , Y value of the vertex (in this case 0 since the vertex is on the x axis 4,0)]
I hope that helped but I have a feeling I did a terrible job of explaining. Good luck with your class!
Domain is the x-axis and range is the y-axisThe domain is all the x-values that a function that take on, and the range is all the y-values that it can be. For instance, if you were given a set of coordinates such as {(2,3), (4,1), and (-9,5)}, you domain would be (-9, 2, 3) for the x-values, and your range would be (1,3,5) for the y-values. If you have to find domain and range for a function, domain typically being found first, you must think of all the possible x-values that could satisfy that equation. If there is a square root, you must ensure that the values do not make that section of the equation negative, and in other cases you must make sure you do not divide by zero. You can then find the range by making a graph or a chart.Domain is/are the value(s) which go under a rule (function of x) and the range is/are the value(s) you get out.
the domain is when the denominator of the problem is set to zero... but i am not sure how to find the range
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
the domain is all real numbers the range is from -1 to +1
Use the function to find the image of each point in the domain. The set of values that you get will be the range. If the function is well behaved, you will not have to try each and every value in the domain.
You need to know the domain first. For each value in the domain there will be a value for the function (or expression). These may not all be different. The set of these values is the range of the equation.
domain is set of real numbers range is set of real numbers
Find all possible "x" and "y" values for domain and range. Then put it in inequality form. For example the domain and range for the equation 2x-3/x-5 would be: Domain: All Reals; x>5 Range: All Reals

the domain is all real numbers the range is from -1 to +1
x = the domain y = the co-domain and range is the output or something e_e
The domain and range are the x and y coordinates of the dot, respectively.
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.
Describe how to find the domain and range of a relation given by a set of ordered pairs.
