Answer:
a. domain: {0, 2, 4}, range: {2, 6, 10}
Step-by-step explanation:
The given diagram depicts a function.
Let us define function:
A function is a mapping of inputs to output.
The left ones are the input of the function while the right side values are the output of the function.
The domain of the function is the set of values that are given as input to the function while the outputs are called range.
so, in the given question
The domain is: {0,2,4} and the range is: {2,6,10}
So, Option A is correct ..

Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
