The period of the function Y=F(x) is 2. When x belongs to-1 and 1, f (x) = the square of x.
That is, when the function y is X=- 1, Y= 1.
When X= 1, Y= 1.
And the function is a periodic function.
So when X=2, the function Y=0.
When X=3, Y= 1.
Y=0 when X=4.
By analogy, Y=0 when X= 10.
And the function Y= logx.
In the interval of (0, 1), the minimum decreasing value is X= 1.
Y=0
exist
(
1
, 10), and the maximum value is X= 10.
Y= 1
So the images of the two functions have 10 intersections.
