Question

What is the midpoint of the x-intercepts of
f(x) = (x – 2)(x – 4)?
(–3,0)
(–1,0)
(1,0)
(3,0)

Answer 1

The x intercepts are always on the x axis, those are the 'zeroes' or 'roots' of the  function

f(x)=(x-r1)(x-r2)...(x-rn) where r1 to rn are roots or intercepts
f(x)=(x-2)(x-4)
the x intercepts are x=2 and x=4
xintercepts are (2,0) and (4,0)
what is between 2 and 4?
3
(3,0) is answer
