Answer:
A.
a = -5
b = -4
c = -3
d = -2
e = -1
B. Yes. It is
Explanation:
The given function is: y = x - 3.
Substituting the values for x, we get values of a,b,c,d,e.
Value of a: a = -2 - 3 = -5
Value of b: b = -1 - 3 = -4
Value of c: c = 0 - 3 = -3
Value of d: d = 1 - 3 = -2
Value of e: e = 2 - 3 = -1
The given function is y = x - 3
This is the equation of a line. Clearly it is a function.
