How Do You Find The Range Of A Function In Math?
The y-values of a function, or the values of its dependent variable, are that function’s range. The range, however, only occurs within the scope of the function’s domain, or the function’s x-values, so in order to determine a function’s range, you need to first be able to determine the function’s domain. In other words, the range of a function is the set of values you get when you plug in the x values in that function’s domain into the function and solve for y. Analyze the function to determine any values of y that won’t allow you to solve for a real value of x. For example, if you had the equation, y=4/(6-x), then 0 can’t be part of the range because when you try to solve for x when the y-value is 0 you get 0=4, which can’t be true. So, for this particular function, the range is all real numbers except 0. Begin by considering the domain of your function to be all real numbers and then eliminate those numbers that don’t allow the function to be solved for a real number. For example, wi
