Answer:
Let f(x)=x^2 -1 and g(x)= x^2 - 2, for x has the domain of all real numbers
a. Show that (f ° g)(x)=x^4 - 4x^2 + 3.
Do we plug g(x) into f(x) ? how do we show that??
b. How could I sketch the graph of (f ° g)(x), for 0 is < or equal to x < or equal to 2.25.
Should I plug it into my calculator and just copy that?
c. The equation (f ° g)(x)=k has exactly two solutions, for x < or equal to x < or equal to 2.25. Find the possible values of k.
