How to determine the graph

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)
