SOLUTION:
Case: Using a solution from a graph to form equations
Given: A graph with several answer points
Required: To form an equation from the graph
Method: From the graph the solution points are: 0, 1 and 3. These are the points where the graph cuts the x-axis.
Therefore if:
[tex]\begin{gathered} x=\text{ 0, 1 or 3} \\ (x-0)(x-1)(x-3)=0 \\ x(x-1)(x-3)=0 \\ f(x)=\text{ }x(x-1)(x-3) \end{gathered}[/tex]
Final answer:
f(x) = x(x-1)(x-3). Option (A)
