Step-by-step explanation:
(d)
step-by-step explanation:
given: the line in the graph passes through points (5,30) and (6,26).
then, the equation of line is:
now, put y=a(n) and x=n,
hence, option d is correct.
the true statements are:
r = set of real numbers
n = set of natural numbers, 1,2,
w = n u{0} = {0,1,}
