Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
Answer: All real numbers
Step-by-step explanation:
−2(x + 3) = −2(x + 1) − 4
-2x -6 = -2x -2 -4
-2x -6 = -2x -6
-2x = -2x
Interchange (switch) the value of x and y in "y = x + 5" as x = y + 5, subtract 5 from both sides and re-write in the form "y = f(x)" as y = x - 5.
<h3>What is an inverse function?</h3>
In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).
The steps required to write the inverse of f(x) = x + 5 include the following:
- Interchange (switch) the value of x and y in "y = x + 5" as x = y + 5.
- Subtract 5 from both sides, we have x - 5 = y.
- Re-write in the form "y = f(x)" as y = x - 5.
