Find (ƒ ∙ g)(x) for the functions provided: ƒ(x) = 2x^2, g(x) = (x + 1)^2

The answer is x^4+1 the rest is how I set it up
(2x^2)(x+1)^2=x^4+1

2((x+2)²)² = 2(x+2)^4 = 2x^4 + 16x^3 + 48x^2 + 64x + 32

Hope this helps.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
