NEED HELP URGENT!!!!!!! Which transformation will map figure Q onto figure Q'?
2 answers:
Answer:
Translation 11 units to the right
Step-by-step explanation:
The figure Q is a trapezoid with vertices at points A(-9,3), B(-6,5), C(-4,5) and D(-2,3).
The figure Q' is also a trapezoid with vertices at points A'(2,3), B'(5,5), C'(7,5) and D'(9,3).
Note that
This means that the transformation is a translation 11 units to the right.

Answer:
see below
Step-by-step explanation:
The tangent function has been shifted upward by 2 units, but there has been no horizontal scaling. Any horizontal offset must be equal to some number of whole periods.
Choices A and B show tan( )+2, the correct vertical offset. However, choice A has a horizontal scale factor of 2. The correct choice is B, which has no horizontal scaling (the coefficient of x is 1) and a horizontal offset of π, one full period.

<em>Comment on horizontal scaling</em>
Horizontal scaling is different from vertical scaling in that using k·x in place of x <em>compresses</em> the graph horizontally by a factor of k. On the other hand, using k·f(x) in place of f(x) <em>expands</em> the graph vertically by a factor of k.
