Question

For a non-linear function, a constant change in $x$ correspond to a constant change in $y$.

• A. does not
• B. does
• C. always

Answer 1

The correct option is A does not

For a non-linear function, a constant change in $x$ does not correspond to a constant change in $y$.

For example: $y=x^2$

It is a non - linear function. How?

Well if we increase the value of $x$, the value of $y$ increases square times.

In simple terms, if we input $x=2$, the value of $y$ will be $4$.

Similarly, for $x=3$, $y$ will be $9$.

The increase in $y$ is not linear or we can say not corresponding to the change in $x$.
