I think the domain is -1 and the range is 2. You may want to double check though.
        
             
        
        
        
Answer: 272
Step-by-step explanation:
Let a1=11
 a2=20
 a3=29
Formula for sequence= 
an=a1+(n-1)d
an = nth term
a1= first term
n= nth position 
d= common difference 
We are looking for the 30th term,so our n=30
d= a2-a1
d= 20-11
d= 9 
Using the formula 
an= a1+(n-1)d
a30= 11+(30-1)9
a30= 11+(29)9
a30= 11+(29×9)
a30= 11+261
a30= 272
Therefore, the 30th term is 272
 
        
             
        
        
        
8x4=32
32 divided by 2 = 16
the answer is 16 square feet
hope this helps :)
        
                    
             
        
        
        
Answer:
option b
1 , 16, 121 , 13456
Step-by-step explanation:
Given in the question a function, f(x) = (x - 5)² 
initial value  = 4
 = 4
First iteration
 f(x0) = f(4) = (4 - 5)² = (-1)² = 1
 x1 = 1
Second iteration
 f(x1) = f(1) = (1 - 5)² = (-4)² = 16
 x2 = 16
Third iteration
 f(x2) = f(16) = ( 16 - 5)² = (11)² = 121
 x3 = 121
Fourth iteration
 f(x3) = f(121) = (121 - 5)² = (116)² = 13456
 x4 = 13456
