Then we have to find the function f(x) which is same as g(x) but shifted 3 units left.
As we know in the given equation f(x) = (a + x)²+ k, x defines the shift of the function and and k defines the shift of a graph on y-axis upwards or downwards.
Here the graph is shifted left so the value of x will be (-3) which defines the shifting of 3 left on x-axis.
Therefore the new function will be f(x) = (x - 3)²
