The range of this absolute value function is -∞ < y ≤ 7
What are the domain and range of a function?
The range of values that we are permitted to enter into our function is known as the domain of a function. In a function like f, this set represents the x values (x). The collection of values that a function can take on is known as its range. The values that the function outputs when we enter an x value are in this set.
Consider the vertical extent of the graph along y axis.
It starts from +7 extends till -∞
So, the range is -∞ < y ≤ 7
