I think its A

Okay, thanks!

you're welcome :P

make sure to medal XD

I think the second one is D? I am just trying to check my answers ><

i think

\[\huge\rm f(x) = −x^2 + 6x + 6\] replace x with 5 and then with 2 solve let me know what you get

f(x)=61
f(x)=22

nope try again

remember it's x^2 so it would be (2)^2

So, would the number be negative? I confused now lol

show ur work how did you replaced x with 2 ?

f(x)=-2^2 +6 x 2 + 6?

yes right

So, then f(x)=-4+6 x 2 + 6?

I see, they were supposed to remain negative

yes right!
so final answer is what

f(x)=-4 plus 12 plus 6
f(x)=8 plus 6
f(x)=14

yes right
now replace x with 5

f(x)=-25 plus 30 plus 6
f(x) = 5 plus 6
f(x)=11

yes right so order pairs are ( 2,14)(5,11)
now plug them into the slope formula

2^2-5^1
over
14^2 -11^1

ohh wait
Y-2 means 2nd y not square

\[\huge\rm (x_1 ,y_1) (1st ~x , 1st ~y)\]

wait what

|dw:1441384007239:dw|

\[\huge\rm \frac{\color{reD}{ y_2} -y_1 }{ x_2 -x_1 }\]
y_2 is just 11

Ohh okay

so same with x_2 and x_1 substitute

2-5
over
14 -11

x should be at the denomiantor

denominator *

Oh, alright, sorry i went to get water

lol

water is already in ur question lol solve that you will get the water

haha, nice one

so, i subtract and then divide or?

yes subtract then divide
PEMDAS rules!

so then, 14-11=3 and 2-5=-3
3/-3=-1?

yes right that's average rate
it's negative so water would decrease or increase ?

decrease

yes right !

falls down ugh samething

lol yea

alright good to go! good luck!

Thank you!

np!
