Answer:
Step-by-step explanation:
The given function is
The range refers to the values of y for which x is defined.
We solve for x to obtain;
This is a polynomial function in y.
x is defined for all values of y.
Therefore the range is all real numbers.
or
The first choice is correct.
Given:
In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15
To find:
The scale factor from PQRS to TUVW.
Solution:
We have,
We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.
The scale factor is:
Therefore, the scale factor from PQRS to TUVW is .
