f(x) = x2 + 4x
for translation
substitute (x-2) to shift 2 units to right, and add 3 to shift 3 units up
h(x) = (x-2)2 + 4(x-2) + 3
for enlargement, multiply by scale factor
g(x) = 1.3 ( (x-2)2 + 4(x-2) + 3 ) equivalent to g(x) = 1.3(x-2)2 + 5.2(x-2) + 3.9
I highly recommend Desmos graphing as a way to view your workings and see how your changes modify the function.
