October 28, 2016 - The range of a function can be written out in words, but to be more mathematically correct, it should be written as an inequality or by using interval notation. Back to our example of f(x) = x^2, writing the range as an inequality, you should have: y > 0, because y is equal to all positive numbers. On screen, is a range expressed using interval notation: Let's look at a practice problem.

Here's a method without calculus.
Let $f(x)=y=\frac{x^2+6}{2x+1}\Rightarrow 2xy+y=x^2+6\Rightarrow x^2-2xy+6-y=0\Rightarrow x=\frac{2y±\sqrt{4y^2-24+4y}}{2}$ Denominator can never be $0$ in this case. So the domain depends only upon $4y^2-24+4y\Rightarrow 4y^2+4y-24≥0\Rightarrow 4(y-2)(y+3)≥0\Rightarrow (y-2)(y+3)≥0\Rightarrow y\in(- \infty, -3]\cup[2,\infty).$
Hence the range of the $f(x)$ is $(- \infty, -3]\cup[2,\infty)$
I guess you know solving inequalities...

To find the range of a function, my first instinct is to check whether the graph has an inverse. We can do this informally using the Horizontal Line Test. If no Horizontal Line intersects the function more than once, then the function has an inverse. With that, we can find $f(y) = x$. The "domain" of $f(y)$ would be the range of the function $f(x)$.
Else, we can use the derivatives of the function to help us find the maximum and minimum which gives us the lower and upper bound of the range of $f(x)$.

r/learnmath on Reddit: How to find Range of function
December 8, 2020 -
Hey so, I jumped a math class and I have a big test coming. I know how to find the domain of a function without a graph, but how do you find the range? The range of a function without a graph, I mean. They discussed it in the class before this one but I wasn't there and the notes aren't telling me much. If there isn't a specific way, are there any tips or tricks? Specifically quadratic functions or functions with square roots in them? My teacher in his notes just replaces the radicand or any other number in a parentheses like thing with [0, infinity)

One way to do it is by inverting the function (swap x and y, then solve for y). The domain of the inverted function will be the range of the original function. Ex: y = x2 + 3, find domain and range This function doesn’t have anywhere where you would be dividing by 0 or taking the square root of a negative, so the domain is (-inf, inf) To find range, first invert function x = y2 + 3 => y2 = x - 3 => y = sqrt(x - 3) The range will be the domain of this inverted function. For x<3, you would be taking the square root of a negative, so the domain of the inverted function is [3, inf). That is the range of the original function.
