Visualize the function and determine the values that alter the range.
Explanation:
The range of a function is different for each function.
The best way (in my opinion) is to visualize the function on a graph. This includes considering all values that change the range. For example, the
Let's use an example of a quadratic function.
If we have a quadratic function of
graph{3(4-x)^2+3 [-14.24, 14.24, -7.11, 7.13]}
We can look at the
In this case, it's any value equal to or greater than
Thus, our range is
In conclusion, recognize which variables change the range, and visualize the function. It becomes much easier to determine the range.
Hope this helps :)
