intercepts and
pictures below.

s = f(t)

A.

(0,6) is on the curve so the s intercept is 6.  It represents the number of t shirts sold in year 0, i.e 600 in year 2000.

The t intercept is the zero of the function, the year we sold zero shirts.  This function doesn't appear to have a zero; it looks like s=0 is an asymptote.

B. As t increases without bound, s=f(t) increases without bound.  That means every year we sell lots more shirts.

C. f(5)=12.5,  f(7)=22

Average rate of change is

475 shirts per year

D

That graph looks like f shifted up by 10 units, i.e. 1000 shirts.

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.
