Step-by-step explanation:
Given : Vertices of Triangle ,
and
To find : Centroid of a triangle
The centroid of a triangle is the point of intersection of the three medians of the triangle.
The formula to calculate the centroid of a triangle is:
Where, are the coordinates of the centroid
Substituting the values in the formula gives us:
Therefore,
Answer:
Option B
Step-by-step explanation:
we have
we know that
<u>The vertical line test </u>is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x
In this problem
The given function passes the vertical line test
therefore
f(x) is a function
<u>The Horizontal Line Test</u> is a test use to determine if a function is one-to-one
If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.
In this problem
The given function fails the horizontal line test
because for f(x)=0 x=-3, x=-1, x=3
therefore
It is no a one-to-one function
