Answer:
a) x changes by 6.5 units
b) y changes by 13 units
Step-by-step explanation:
a. Over this interval, how much does x change by?
Initially, we have that x = 2.
In the end, we have that x = 8.5.
So x changes by 8.5-2 = 6.5 units
b. Over this interval, how much does y change by?
Initially, when x = 2, we have that y = 2x + 11 = 2*2 + 11 = 15
In the end, when x = 8.5, we have that y = 2*8.5 + 11 = 28
So y changes by 28 - 15 = 13 units
x=2.5
5x = 5(2.5) = 12.5
I believe 12.5 is the answer

Answer:
Option 3 - f(x)= 4x, 
Step-by-step explanation:
To find : Which two functions are inverses of each other?
Solution :
Two functions are inverse if 
Now, we find one by one
1) f(x)= x, g(x) = -x

Not true.
2) f(x)= 2x, 

Not true.
3) f(x)= 4x, 


i.e.
is true.
So, These two functions are inverse of each other.
4) f(x)= -8x, 

Not true.
Therefore, Option 3 is correct.
