3. Predict and sketch the shape of the graph of h[x]=x^2 + Cos[x] on [-10,10].
3. Predict and sketch the shape of the graph of h[x]=x^2 + Cos[x] on [-10,10].
Many students may not take into consideration the different scales on the graph when they draw their sketches. Their conjectures may look like the following plot.:
Input :=
Plot[x^2 + 20 Cos[x], {x, -10, 10},
PlotRange -> {-20,100}]
Output = -Graphics-
