The fourth listed answer:
Domain: All Real numbers
Range : { f{x) | f(x) 0, f(x) = 1 }
Step-by-step explanation:
The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.
The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value "x" of the domain. The line with positive slope extends to all f(x) values that are 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Double Angle Identities: cos 2A = 1 - 2sin²A
sin 2A = 2sinA · cosA
<u>Proof LHS = RHS</u>
y cos 2A + x sin 2A = y
x sin 2A = y - y cos 2A
x sin 2A = y(1 - cos 2A)
This is a TRUE statement since it was given that
