Question

If $f\left(x\right)$ is a cubic polynomial then what will happen to the graph of $f\left(x\right)+1$?

• A. Shifts $1$ unit upwards
• B. Shifts $1$ unit downwards
• C. Shifts left
• D. Data Inadequate

Answer 1

The correct option is A Shifts $1$ unit upwards

In general for $f\left(x\right)+k$, the graph shifts $k$ units upwards if $k$ is positive and shifts $k$ units downwards if $k$ is negative.
So here the graph will shift $1$ unit upwards for $k>0$
