Question

What is the domain of the function in the graph?d12011008060402006 7 8 9 10 11 12 eOA. 40 ≤e ≤ 80OB. 40 ≤ d ≤ 80OC.6 ≤e ≤ 11OD. 6 d≤ 11

Answer 1

The domain of a function is all values of x (horizontal axis) the function can assume.

Looking at the graph, the values of x go from 6 to 11, including both ends.

Therefore the domain of this function is:

$6\leq x\leq11$

So the correct option is C.

(the variable in the x-axis is "e", so that's why the answer is C and not D).
