If the graph of the function (which is a line) does not
intercept the x axis, that means that the equation of the line has no real
solutions.
In other words, there are no such values for x
to cancel the equation of the line.
When the graph is
intercepting x axis, then y = 0.
Let f(x) =
y.
Since the graph is not intercepting x axis, then y
> 0 =>
x-2m+2 >
0
We'll isolate x to the left
side:
x > 2m - 2
Since
x > 0 => 2m - 2 > 0
We'll divide by
2:
m - 1 > 0
m >
1
The interval of possible values for m, for
the graph of f(x) not to intercept x axis, is: (1 ,
+infinite).
