Need some clarification

G.4) Plot3D versus ParametricPlot3D G. 4. a. i) Go with f[x] = x e- and explain with words and pictures what you think that this plot represents: In[5] = Clear [f, x]; {a, b} = {-0.6, 8); f [x_] = x^2 E^(-x) ; raw = Plot[f[x], {x, a, b), PlotRange -> All, AspectRatio -> 1/2] Out(8]= 0.6 TTTTTTT 0.5 0.4 0.3 0.2 2 4 6 8Stay with the same function x] and the same values for a and b and 1001-: at: |n[1?}:= ' parametric = ParametricPIO'tx, fIx]}, {x, a, b}, PlutRange -> .I-"I.11j AspectRatio -> 1f2] {MEET}: See the two plots sidebyside: |n[151:= l ShWIGraphicsArrayI {rang parametric} I] cum]: 13.5153 ll] 15 211] ll] 15 2E] Say what happened, and try to explain why it will happen no matter what function x] you go with
