Answer:
C) Exponential; y= 14(0.90)^x
Step-by-step explanation:
Given is a table in
x 0 1 2 3 4
f(x) 14 12.6 11.34 10.206 9.185
On observing the pattern we find that whenever x increases by 1, y decreases.
But the decrease is not constant hence relationship cannot be linear for x and y.
The change of y follows some pattern as a geometric sequence with common ratio as 0.9
I term is for x =0 and then x increases by 1 unit.
Hence when x=x, we have
Option C is right answer.
