Given:
The equation is:
The graph of the and
are given on a coordinate plane.
To find:
The solution of the given equation from the given graph.
Solution:
From the given graph it is clear that the graphs of and
intersect each other at points (1.24,5.24) and (16,20).
It means the values of both functions and
are equal at
and
.
So, the solutions of given equation are and
.
Therefore, the correct option is only F.
Answer:
Step-by-step explanation:
has the form
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
