Graphs are used to represent functions, equations and polynomials
The equation of the function is given as:
[tex]f(x) = 2(x - 1)(x + 1)(x + 2)[/tex]
Set x = 0
[tex]f(0) = 2(0 - 1)(0 + 1)(0 + 2)[/tex]
[tex]f(0) = -4[/tex]
The above means that the graph passes through the point (0,-4)
Next, set f(x) to 0
[tex]2(x - 1)(x + 1)(x + 2) = 0[/tex]
Divide through by 2
[tex](x - 1)(x + 1)(x + 2) = 0[/tex]
Solve for x
x = 1, -1 or -2
The above means that the graph passes through the points (-1,0), (-2,0) and (1,0)
