we have
using a graph tool
see the attached figure
So
1) the domain of the function is all real numbers-----> interval (-∞,∞)
2) the range of the function is the interval [-1, ∞)
3) the function decrease on the interval (-∞,2)
4) the function increase on the interval (2,∞)
5) the function has two x-intercepts-----> (1,0) and (3,0)
6) the function has one y-intercept-----> (0,1)
therefore
the graph in the attached figure
13 = 13
45= 3* 3* 5
GCF (13, 45)= 1.
Because GCF (13, 45)= 1, 13 and 45 are relatively prime. Therefore, 13/45 in its simplest form is still 13/45~
