the math club decided to have a car wash to raise money for competition expenses the graph below shows the relationship between cars washed and earnings (in dolloars) what is the domain of the graphed function

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

b. f(x) = –√x + 3this is the correct answer
