Answer:
a.) f(2) = 3
b.) if f(x) = 2
x=3
Step-by-step explanation:
Here you must notice that on the graph where x is 2, y or f(x) is at 3. This means that the answer where in the function of x, where the input 2, the output or y/f(x) is 3
And if the output is 2, the input is 3 as proven above.

Answer:
Option A is correct.
Solution for the given equation is,
Step-by-step explanation:
Given that : Let then our equation become; .....[1]
A quadratic equation is of the form:
.....[2] where a, b and c are coefficient and the solution is given by;
Comparing equation [1] and [2] we get;
a = 2 b = -1 and c =-1
then;Simplify:or and
Simplify:y = 1 and
Substitute y = cos x we have;⇒and⇒
The solution set:
Therefore, the solution for the given equation is, 0 degrees
