Question

Suppose y=f(x) + k. What effect does k have on the parent function

Answer 1

Adding 'k' to
`y=f(x)` translates it 'k' units upwards.

Explanation:

We are given that,

The parent function,
`y=f(x)` is changed to
`y=f(x)+k`

That is, transformation is applied to
`y=f(x)` in order to obtain
`y=f(x)+k`.

As, we can see that the constant 'k' is added to the parent function.

This means that, the function
`y=f(x)` is shifted 'k' units upwqards.

Hence, adding 'k' to
`y=f(x)` translates it 'k' units upwards.
