this simplifies to a linear function
so its graph will be a straight line
it simplifies to
4 ( x + 1)(x - 2)
2(x + 1)
= 4(x - 2) / 2
= 2(x - 2)
= 2x - 4
where will the discontinuities be?
- sorry theres just one discontinuity
although it simplifies to a linear function and the graph will be a line except, because it is a fraction there will be a point where there is no value for f(x) and it can be represented on the graph by a small open circle.
- this is called a 'hole' in the graph
This one is confusing me a little because the way to find holes is to set the factor common to top and bottom of the fraction to zero and solve for x
in this case the factor is x + 1
x + 1 = 0 so x = -1
that is a hole at x = -1
and corresponding value of f(x) = -6
oh OK - i got confused That is the answer
