A horizontal translation is expressed by transforming
![f(x)\mapsto f(x+k)](https://tex.z-dn.net/?f=f%28x%29%5Cmapsto%20f%28x%2Bk%29)
If
is positive, the function is translated to the left. If
is negative, the function is translated to the right.
So, a 3-units left shift is given by
. So you have
![f(x)=2x^2-1 \implies f(x+3)=2(x+3)^2-1](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2-1%20%5Cimplies%20f%28x%2B3%29%3D2%28x%2B3%29%5E2-1)
