Question

Example of an nonlinear function?

Answer 1

f(y)=a^y

y=0,1,2,3....a=integer

here value of f(y) varies non linearly with change in the value of y..

so that when u plot a graph of this equation this will lead to a line or a curve which is not a straight line...

all functions whose graph is not a straight line are called nonlinear function

Answer 2

y=x^2 (a parabola)

a linear function is a straight line like y=2x

Answer 3

x^#

# can equal any number you want and the function won't be a straight line.
