Question 1.
Let f(x)
x²sin
%3D
a) Find a function g(x) such that -g(x) < f(x) < g(x) for all real numbers x.
b) Use the inequality -g(x) < f(x) < g(x) to find lim f (x). ( State the theorem)
c) In GeoGebra, sketch the graph of the functions: -g(x), f(x), g(x).
Use the graph to demonstrate that the inequality in part (a) and the limit found in part (b) are in fact
x-0
correct.
