is continuous over its domain, all real

.
Meanwhile,

is defined for real

.
If

, then we have

as the domain of

.
We know that if

and

are continuous functions, then so is the composite function

.
Both

and

are continuous on their domains (excluding the endpoints in the case of

), which means

is continuous over

.

Answer:
Hoping someone else can answer with more confidence, but here's what I have:
on the left hand side:
upper is partial/penumbral lunar eclipse
lower is total solar eclipse
on the right hand side:
on the top: it's impossible for the moon to be behind the sun, so I'm not sure what they want there
middle is total solar eclipse
bottom is partial/penumbral lunar eclipse
Hope I helped at least a little
Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) =
- 1
fg(x) = f (
- 1) , we just put in the value of g(x) , the next thing is to substitute
- 1 for the value of x in f(x) , that is
fg(x) = -2(
- 1) - 1
fg(x) = -2
+ 2 - 1
fg(x) = -2
+ 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 (
+ 1
fg(-5) = -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
