Step-by-step explanation:
The meaning of f(2) is x = 2. The question is asking us to find the y-value when x = 2.
According to the graph, when x = 2, y is somewhere between 8 and 10. The graph looks like it intersects right in the middle of those 2, so the y-value when x = 2 would be 9.
Therefore, f(2) = 9.
Answer:
QUESTION 1
The given system of equation,
We simplify to get.
The correct answer is option A.
1.
A.) (4, −2)
2.
x = -7
y = 2
3.
x = 5
y = 14
QUESTION 2
The given system of equations is
and
We make y the subject in equation (2) to get,
We put equation (3) into equation (1) to obtain,
We group like terms to get,
This implies that,
we divide through by to get,
Hence the x-coordinate is
QUESTION 3
The given system is
and
We make the subject in equation (2)
We put equation (3) into equation (1) to obtain,
We expand the bracket to get,
Group like terms to get,
We simplify to get;
This implies that,
Therefore the y-coordinate is 14.

Step-by-step explanation:
Statistics is defined as a body of techniques used to facilitate the collection, organization, presentation, analysis, and interpretation of information for the purpose of making better decisions : TRUE statement.
Statistics helps the people to use limited sample to make accurate conclusions about a greater population. In stats we use tables, charts and graphs to present the data to draw some conclusions.
