What is the average rate of change of f(x) = -x2 + 3x + 6 over the interval -3 sxs 3? O A-2
O B. -1
O C. 3
O D. 6

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
