Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if any, and any symmetry with respect to the x-axis, the y-axis, or the origin.
A. function
domain: {x|x = 6 or x = -8}
range: all real numbers
intercept: (-8, 0)
symmetry: x-axis
B. function
domain: all real numbers
range: {y|y = 6 or y = -8}
intercept: (0, -8)
symmetry: none
C. function
domain: all real numbers
range: all real numbers
intercept: (0, -8)
symmetry: none
D. not a function

Solve the problem.An office desk costs $6000. After 5 years, it depreciates to a value of $3500. Assuming linear depreciation, answer the following.(i) Write a linear equation that gives the value of the desk, y, in terms of the number of years after it was purchased, x.(ii) Using the equation found in part a, find the value of the desk after 7 years.(iii) After how many years would the desk have no value?
A. (i) y = 6000 - 500x (ii) $3500 (iii) 12 years B. (i) y = 6000 - 400x (ii) $2500 (iii) 12 years C. (i)y = 6000 - 500x (ii) $2500 (iii) 12 years D. (i) y = 6000 + 500x (ii) $9500 (iii) 20 years
