Question

To raise money, a school band is selling tickets to a breakfast. The graph on the coordinate grid below shows the functional relationship between the number of tickets sold and the revenue. What is the domain of the function?a) integers from 0 to 400b) real numbers from 0 to 500c) integers from 0 to 80

Answer 1

the domain of function represents the value of the function on the horizontal axis that is the x-axis,

here we can see that line is starting from origin that is (x, y) = (0, 0) and it is ending at (x,y) = (80, 400)

so x is varying from

x =0 to x = 80

so it the domain of the function

so the answer is option C
