Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Multiply by -1 both sides ( remember that the sign of the inequality change)

The solution is the interval ----> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of x=-4 (close circle)
see the attached figure
Answer:

The i is usually the square root of -1 which does not exist in the real number system.
The number given is a mixture of real and complex and is classified as complex.
The answer is C
You could make this super easy by letting g(x) =

and f(x) =

and then the composition would be to take g(x) and put it into the x in f(x) to give you your
