Question 10 What is the domain of ƒ(x) if ƒ(x) = x – 4?
A
all real numbers

B
all real numbers except 4

C
all integers

D
all integers except 4

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
