Answer:
[-16,-4]
Step-by-step explanation:
We are given that

Domain=[-2,1]
We have to find the set of range values of f(x).
Substitute x=-2


Substitute x=1

Range of f(x)=[-16,-4]
Hence, the set of range values of f(x)
[-16,-4]
Answer:
Okay so for the first box i should be x<-5 and the other box should be -5<x
Step-by-step explanation:
Answer:
the common difference is 6.
Step-by-step explanation:
Given;
first term of an AP, a = -7
let the common difference = d
The third term is written as;
T₃ = a + 2d
The eight term is written as;
T₈ = a + 7d
The ratio of the eight term to third term = 7:1

Therefore, the common difference is 6.
Answer:
r = 3 1/4
Step-by-step explanation:
Here, we want to find the value of r given the values
Firstly, we will write r as the subject of the formula
U = π ( r + h)
U/π = r + h
r = U/π - h
Now substitute;
U = 16 1/2 = 33/2
h = 2
π= 22/7
r = 33/2/22/7 - 2
r = (33/2 * 7/22) - 2
r = 21/4 - 2
r = (21-8)/4
r = 13/4 = 3 1/4
