AB = BD = 10cm
Now using the Pythagorean theorem:
26^2 = 10^2 + BC^2
Simplify:
676 = 100 + BC^2
Subtract 100 from both sides:
576 = BC^2
Take the square root of both sides:
BC - sqrt(576)
BC = 24 cm
The given polynomial graph can be classified as; surjective
<h3>How to Interpret Mapping Functions?</h3>
A General Function points from each member of "A" to a member of "B".
It never has one "A" pointing to more than one "B", so one-to-many is not OK in a function
Injective means we won't have two or more "A"s pointing to the same "B".
So many-to-one is not okay (which is Okay for a general function).
As it is also a function one-to-many is not Okay.
Surjective means that every "B" has at least one matching "A". There won't be a "B" left out.
Bijective means both Injective and Surjective together.
It's more like a "perfect pairing" between the sets: every one has a partner and no one is left out.
So there is a perfect "one-to-one correspondence" between the members of the sets.
Looking at the given graph, it is not a one to one as it is clearly surjective.

In the attached picture you have the graph of
. To evaluate the function at
, you'll have to start from 0 on the x axis, and travel vertically until you meet the graph.
In this case, if you start from the origin, you have to go upwards one unit, until you meet the graph at (0,1).
So, if
