The x-intercepts are indeed -1 and 1.
The increasing intervals are listed as (-1, 0) u (1, infinity) not because -1 and 1 are not included points of the function, but because the function is not differentiable in those points, so you can't tell whether the function is increasing or decreasing there.
The scale factor equal to 1 will have No Effect on the dimensions of the image being scaled .
In the question ,
it is given that ,
the scale factor is = 1.
we have to find the effect of change ;
we know that ,
when the value scale factor is greater than 1 , then dimensions of new image is larger than original .
when the value of scale factor is 1 , then there is no change in the dimensions of the image .
when the value of scale factor is less than 1 , then the dimensions of new image is smaller than the original .
Therefore , if the scale factor is 1 , then there is no change in the dimensions of the image .

1cm = 10mm
15.24cm x 10 = 152.4mm
Hope this helps!!!
