Question
The function ƒwhere ƒ(x)=x² -4, is defined for all real values of x (The domain can be
any real number)
(a) Find the values of f(-3), ƒ(-2), ƒ(-1), ƒ(0), ƒ(1), f(2), ƒ(3). Hence complete the table

f(x)
-3
(b) Plot the points (you can use graph paper) and draw the graph of f(x)=x² – 4
(c) Use your graph to write down the range of y= f(x). (Remember you can input any
value of x.)
(d) Write down the solutions of the equation x² – 4=0. That is the values of x for which
ƒ(x)=0
(e) Explain why ƒ is a many-to-one function and not a one-to-one function.
