The function is expressed as
h(x) = (x - 2)(x - 4)
It can be rewritten as
y = (x - 2)(x - 4)
We would substitute values of x into the equation and find corresponding values of y. We have
When x = - 2, y = (- 2 - 2)(- 2 - 4) = - 4 * - 6 = 24
When x = - 1, y = (- 1 - 2)(- 1 - 4) = - 3 * - 5 = 15
When x = 0, y = (0 - 2)(0 - 4) = - 2 * - 4 = 8
When x = 1, y = (1 - 2)(1 - 4) = - 1 * - 3 = 3
When x = 2, y = (2 - 2)(2 - 4) = 0 * - 2 = 0
We would plot the corresponding x and y values on the graph as shown below
