Answer with explanation:
The meaning of bijection for two sets X and Y is each and every element of X is uniquely related with element of set Y and when you take the inverse mapping every element of set Y is uniquely related with each and every element of Set X.
The two sets given are
X=(0,1]---------Semi open or Semi closed Set
Y=(0,1)---------Closed set
Between any two real numbers there are infinite number of real numbers.So cardinal number of both the sets is infinite.
There can be infinite bijection between these two sets as both sets have infinite number of elements.
X Y
0.1 ------------- 0.01
0.2 ------- 0.02
0.3 -------- 0.03
0.4 --------- 0.04

The answer to this is C.17
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>
How many roots has the given polynomial?</h3>
We have the polynomial:
To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.
