Answer:
The answer is (g°f)(-1) = 27
Step-by-step explanation:
* (g°f)(1) ⇒ means make the domain of g is the range of f
- At first find the value of f(-1)
- Take the answer and substitute it as the value of x for g
- So the range of f is the domain of g
∵ f(x) = 4x + 7
∵ The domain of f = -1 ⇒ x is the domain
∴ f(-1) = 4(-1) + 7 = -4 + 7 = 3 ⇒ f(-1) is the range
∵ g(x) = x³
∵ x = f(-1) = 3 ⇒ the domain of g
∴ g(3) = 3³ = 27 ⇒ the range of g
* (g°f)(-1) = 27

Answer:
-5
Step-by-step explanation:
On the number line, the arrow is from -2 (opens) to the left; that means solutions will be any values less than -2
So
-5 < -2 : YES ( solutions will be any values less than -2)
-2 = -2 : NO (solutions will be any values less than -2)
0 > -2 : NO (solutions will be any values less than -2)
3 > -2 : NO (solutions will be any values less than -2)
Answer
- 5
It would be -4. subtracting a positive is the same as adding a negative
