Vertex = (3, -1), 2nd point = (4, 0)

Step-by-step explanation:

f(x) = (x - 2)(x - 4)

The x-intercepts (when y = 0) are: x - 2 = 0 and x - 4 = 0  → x = 2 & x = 4

The x-value of the vertex is the midpoint of the zeros.  The midpoint between x = 2 and x = 4 is x = 3

The y-value of the vertex can be found by plugging the x-value (above( into the given equation: f(3) = (3 - 2)(3 - 4)  =  (1)(-1)  =  -1

So, the vertex is (3, -1)   ←    PLOT THIS COORDINATE

Additional points are: (2, 0) and (4, 0)  ←  PLOT ONE OF THESE
