For both questions: Let f(x) and g(x) be real-valued functions defined onR(All real numbers).

i.) Calculate Δ(f(x)g(x)

ii.) Let f(x) = x^2*2^x. Use (i) to calculate Δf(x)

Read: "Let f of x equal x squared times 2 to the x. Use part i to calculate delta f of x.

For i, I know that the derivative is 1, but I am unsure if that is the answer or how I can use that to get my answer, and obviously if I don't have part i correct I cannot attempt part ii.
