Answer:
B
Step-by-step explanation:
Using the expansion
tan(x - y) =
, then
tan(x -
)
= 
note that tan( -
) = - tan(
) = - 
= 
=
→ B
Answer:
By definition, the slope of a vertical line is undefined. Because the value of x is always equal to 4 it is never equal to 0 therefore there is no y-intercept.
Step-by-step explanation:
Answer:
the answer is 4!!!!!!!!!!!!!!
Answer:
Option C. y= ( -x)^2 -4
Step-by-step explanation:
If we have a function
and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:

In this case we want to move the function 4 units down, then:

Finally, to reflect the function on the y-axis. must do 
Then we have the following function:

The answer is option C
