Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change =
=
= - 4 → C
Answer:
I can't find one of these
Step-by-step explanation:
In my way:
let x=0
2 (0)+y=5
y=5
Answer:
4
Step-by-step explanation:
Slope= y2-y1/x2-x1
(1,5) is placed as (x1,y1) and (-1,-3) is placed as (x2,y2)
Plug it in
-3-5/-1-1
Simplify
-8/-2 = 4
Slope=4
x= -4 and x=8
f(x) =6║x-2║+3
39= 6║x-2║+3
36=6║x-2║
6=║x-2║
-(x-2)=6
-x+2=6
x=-4
x-2=6
x=8
