i do not understand what this question is asking
let me try to read it again

first off you have two functions

yes function a and b

not "a function"
but if you get 3 for the first one, it means
\[f(x)=x^2+2x=3\]

oooh i see what it is asking

plug in 3 in to each function and see which one gives 3 as an answer

ive tried that but i keep getting 15 or -15

for the first one?

the question asks "which function gices the value 3 when plugged in with 3 or -3 ?"

so evidently it is not A since
\[3^2+2\times 3=15\]

however if you try B you should get it

yeah true
but if you plug in 3 in to the second one, you should get 3 out

btw the second one does not get 0 if you plug in 3

hmmm hold on a second

\[f(x)=x^2+2x\]
\[f(-3)=(-3)^2+2\times (-3)\] try that

you do not get \(-15\) because \((-3)^2=9\) not \(-9\)
you should get \(9-6=3\) for A

that was correct thank you so much can i ask you just one more question

sure

how many adults would have to attend for the organizers to raise the targeted amount.? sorry

& how would you set it up as a equation with the given information

can you please help me on this question
