The varsity basketball team started selling t-shirts online in 1994. the number of t-shirts sold online, s, is modeled by the graph below, where t = 0 represents the year 2000. pls with the parts,

Answer A):

s-intercept means y-intercept as s ( number of t-shirts) is graphed along y-axis.

We see that graph crosses y-axis at (0,6)

So that means s-intercept is = (0,6)

s-intercept (0,6) indicates that t-shirts sold in year 2000 is 6 thousand.

t-intercept means x-intercept as t ( year) is graphed along x-axis.

We see that graph doesn't cross x-axis

So that means there is NO t-intercept.

No t-intercept means there was no year after production start when they sold 0 t-shirts.

----------------------

Answer B):

From graph we can clearly see that as t increases then f(t) also increases so for the end behavior we will write "increases" in the blank space.

It means as the time increases then sales also increases.

----------------------

Answer C):

Average rate of change can be calculated by formula of slope which is:

----------------------

Answer D):

Given that g(t) is sum of T-shirts sold online and at the basketball games where sold -shirts in basketball game = 1000 T-shirts. But f(t) is in hundreds so that means 1000 T-shirt will make increment of 10 in value of f(t) hence graph of g(t) will be just 10 unit above than graph of f(t).

Then equation of g(t) will be:

Hence final answer is
