Simplify your answer as much as possible.

raffle_snaffle · Answer

plug in x = 6, what is g(x) = ?

anonymous · Answer

g(6) = 57
g(2) =13

anonymous · Answer

correct?

phi · Answer

how did you get g(2) = 13 ?
can you show what you did ?

phi · Answer

oh,  you ignored the minus sign in front of - x^2 ?

anonymous · Answer

$$g(x)= -(2)^2 + 3(2) + 3$$
$$g(x)= 4+6+3 $$
$$g(x)= 10+3 = 13$$

raffle_snaffle · Answer

Once you find g(2) and g(6) you can find the average rate of change given by 

Average rate of change = g(6) - g(2)

phi · Answer

except the minus sign is not inside the square
it is -1 *  x^2  or -1 * 2*2  = -4
