Option B. It represents a nonlinear function because its points are not on a straight line.
Step-by-step explanation:
Let
we know that
If point A,B and C are on a straight line
then
The slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to
Find the slope AB
substitute in the formula
Find the slope AC
substitute in the formula
so
Points A, B and C are not on a straight line
therefore
It represents a nonlinear function because its points are not on a straight line
