Basically, whatever is in the parentheses next to the , you plug in to the expression that is the function.
ex:
Okay, onto the problems:
a)
First, plug in 14, since that is given:
and solve.
So, 41 is the answer to a.
b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.
-31 is the answer to b.
c) For this problem, you have to do a bit of algebra.
First, take the base function f(x):
Then, set f(x) = 24:
and solve by isolating x.
25/3 is the answer to c.
From the picture, we can see the pair, bear in mind that terminal point pair is really the (x,y) pair or namely the (cosine, sine) pair, so we know what the cosine and sine are.
