This time we will get a horizontal translation. If \(a\) is positive then the graph will translate to the left. If the value of \(a\) is negative, then the graph will translate to the right.
If \(f(x) = x^2\) then \(f(x + a) = (x + a)^2\). The value of \(a\) represents a negative horizontal translation in the graph. If \(a\) is positive, then the graph will translate to the left.
