I’ll give brainliest for this one question to be explained throughly. brad made a graph showing how many students were absent from school every day last week.

use the graph to answer the questions.

4. Is the relation represented by the graph a function? Why or why not?

We can easily determine whether or not an equation represents a function by performing the vertical line test on its graph. If any vertical line intersects the graph more than once, then the graph does not represent a function. If an algebraic equation defines a function, then we can use the notation f(x)=y.

the 3rd option is right

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
