Answer:
Step-by-step explanation:
Answer: x = 2
Step-by-step explanation:

Replace y in the first equation by the value of y in the second equation.

Given:

To find:
The values of f(2) and f(5).
Solution:
If an ordered pair
is in the function
, then
.
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get

In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get

Therefore, the value of f(2) is 3 and the value of f(5) is 6.

Answer:
Vertical Stretch, Reflection over the x-axis
Step-by-step explanation:
y = −f(x) is a reflection of the graph y = f(x) in the x-axis
Reflection over the x-axis
a f(x) If |a| is greater than 1, then vertical stretch.
Vertical Stretch
