-2 = -(x-8)
-2 = -x + 8 ( - * + = - and - * - = + )

-2 - 8 = -x +8 - 8
-2 - 8 = -x
-(2+8) = - x
-10 = -x | * (-1)

x=10

Answer:

Step-by-step explanation:

f(x)=x^+4x+2 First, let's evaluate when x=3, x=4 and x=5.

f(3) = 3²+4(3)+2 = 9 + 12 + 2 = 23

f(4) = 4²+4(4)+2 = 16 + 16 + 2 = 34

f(5) = 5²+4(5)+2 = 25 + 20 + 2 = 47

Now, let's find the rate of change.

34 - 23 = 11

47 - 34 = 13

Finally, the average rate of change.

(11 + 13) / 2 = 12
