Given:
The vertices of a triangle ABC are A(-2,1), B(-1,4) and C(-4,5).
Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.
To find:
The point B'.
Solution:
If a figure reflected over x-axis, then
If a figure reflected over y-axis, then
If a figure rotated 180 degrees about the origin, then
So, the coordinate of point B' are (-1,4).
Therefore, the correct option is A.
ANSWER
C. The left end goes up; the right end goes down.
EXPLANATION
The given function is
We analyze the end behavior of this function using the leading term.
The leading term of this function is:
Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.
In other words, the left end of the graph goes up and the right end goes down.
The correct option is C.
