The number of subscribers to a magazine since the magazine changed its format can be modeled by the linear equation y = 504.2x + 29,165.8, where x is the number of months since the format change and y is the number of subscribers. Part I Explain what the number 504.2 represents in this context. Take into account the fact that 504.2 is not a whole number in your explanation. Part II Explain what the number 29,165.8 represents in this context. Take into account the fact that 29,165.8 is not a whole number in your explanation. Part III Fill in the table below with the expected number of subscribers to the magazine for each of the given number of months since the format change. Enter the numbers of subscribers as whole numbers by rounding, when necessary. Number of Months Since Format Change Number of Subscribers 4 5 7 9 11 15 16 19 20 22

you need to know that the corresponding sides and angles are the same.

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:

just remember - if you can look it up, so can i.   i really hope that your submitted assignment doesn't look like any i find here, or like any other student's.
