Points Lying on the undefined curve are
x : 0 1 2 3 4
f(x): 3 7 29 87 199
Plotting the points on the coordinate plane
As you will see, the value of x increases , value of y increases .
It is not linear, because slope between two points is not same.
Neither quadratic nor cubic , it is not cutting x axis .
So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.
So, option (D) Exponential ,Function word is the right word Describing these points.
