Answer: Yes
Explanation: The equation has 3 variables
Draw a right triangle ABC, with m(CAB)=∅.
Let CB=7 units, AC=8 units, so by the Pythagorean theorem:

(units)
so we have drawn a triangle where sin∅=7/8
in this triangle, cot∅=(adjacent side)/(opposite side)=

Answer:
Are you sure the question is right?
The given function is

A . f(4) means we have to evaluate the function when x = 4.

<h2>Therefore, f(4) = 14.</h2>
B. f(x) = 50 means we have to evaluate the function when y = 50.-

<h2>Therefore, f(16) = 50.</h2>
C. f(-5) means we have to evaluate the function when x = -5.

<h2>Therefore, f(-5) = -13.</h2>
D. f(x) = -34.

<h2>Therefore f(-12) = -34.</h2>
