Label the axes and show where the solution is located on the graph.The value, v, in hundreds of dollars, of Juan's computer is approximated by  where t is the number of years since he first bought the computer.(a) Sketch the graph the equation.(b) Find the missing coordinate for the ordered pair solution (4, ? ).(c) Interpret the point from part (b).(d) Find and interpret the y-intercept.(e) What does the x-intercept represent in this problem?

A. (a)

(b) (4, 600); (c) The value of Juan's computer
is $600 after 4 years of ownership.; (d) The
y-intercept, (0, 1200) indicates that the value
of Juan's computer was $1200 when he first
bought it.; (e) The x-intercept, (8, 0) 
indicates that after 8 years, Juan's computer
will be worthless ($0).
B. (a)

(b) (4, 1800); (c) The value of Juan's computer
is $1800 after 4 years of ownership.; (d) The
