Answer:
C
Explanation:
The domain of a function is the span of x-values.
And the range of a function is the span of y-values it covers.
From the graph, we can see that the span of x-values the graph covers goes from x=1 to x=6.
In other words, the domain is all numbers between 1 and 6 including 1 and 6.
In an inequality, this is:
For the range, we can see that the lowest the graph goes is y=1, and the highest it goes is y=7.
So, the range is all numbers in between 1 and 7 including 1 and 7.
In an inequality, this is:
Thus, the correct answer is C.
D is half correct, but the domain and range is flipped, so that may be your mistake. Be more careful next time!
