Answer:
B.7
Step-by-step explanation:
This one is pretty simple, just insert each number to find which one is true.
2(7)<18
14< 18 (true)
2(9) < 18
18< 18 (false because it said less than not less than or equal to)
2(36) < 18
72< 18 (false)

Answer:
A) 
B) 
C) 
Step-by-step explanation:
So we have the equation:

Let's write this in function notation. Thus:

A)
To flip a function over the x-axis, multiply the function by -1. Thus:

Simplify:

B) To flip a function over the y-axis, change the variable x to -x. Thus:

Simplify:

C) A reflection over the line y=x is synonymous with finding the inverse of the function.
To find the inverse, switch x and f(x) and solve for f(x):

Switch:

Subtract 4 from both sides:

Divide both sides by 5:

And we're done :)
