@aaronq or ANYONE THAT CAN HELP

OpenStudy (anonymous):

Given the function g(x) = 8x - 2, compare and contrast g(-2) and g(4). Choose the statement that is true concerning these two values. The value of g(-2) is larger than the value of g(4). The value of g(-2) is the same as the value of g(4). The value of g(-2) is smaller than the value of g(4). The values of g(-2) and g(4) cannot be compared.

OpenStudy (anonymous):

g(-2)=8(-2)-2=-18 g(4)=8(4)-2=30

OpenStudy (camerondoherty):

All you gotta do is sub x for the given number: For g(4): \[g(4)=8(4)-2\] For g(-2) \[g(-2)=8(-2)-2\]

OpenStudy (camerondoherty):

then solve

OpenStudy (anonymous):

g(4)=8(4)-2........g(4)=30-2....30 g(-2)=8(-2)-2.....g(-2)= -16-2...-18

OpenStudy (camerondoherty):

The first one equals: 30 The second one equals: -18 like @lacrosseplayer22 said

OpenStudy (anonymous):

I said it toooo!

OpenStudy (anonymous):

u too Venny

OpenStudy (camerondoherty):

lol

OpenStudy (cp9454):

i have a doubt , how is that comparing it's just getting the desired value. please let me know anyone.

OpenStudy (anonymous):

...

OpenStudy (anonymous):

We didn't fully answer it. We just gave the values to be compared...

OpenStudy (anonymous):

I don't think it's comparing. It should be the value of g(-2) is smaller than the value of g(4)....Correct me if I'm wrong @camerondoherty or @Venny

OpenStudy (camerondoherty):

@ZekeWars the answer would therefore be B because the value of g(4) is 30 which is greater than the value of g(-2) which is -18

OpenStudy (anonymous):

B says that they are the same. it should be C :)

OpenStudy (anonymous):

>.<

OpenStudy (camerondoherty):

Yes @lacrosseplayer22 you are 100% correct and sorry i was meaning c lol

OpenStudy (camerondoherty):

xD

OpenStudy (anonymous):

its C

OpenStudy (camerondoherty):

but what i said was true

OpenStudy (anonymous):

MY BRAIN LOL

OpenStudy (camerondoherty):

just got the options mixed up lol

OpenStudy (anonymous):

ok thanks all, can you help me with my last one when i post it? :P

OpenStudy (camerondoherty):

@ZekeWars is C for sure! Because the value of g(4) is 30 which is greater than the value of g(-2) which is -18

OpenStudy (anonymous):

I think he means a different question....

OpenStudy (camerondoherty):

ik that

OpenStudy (camerondoherty):

im just officially telling him

OpenStudy (anonymous):

lol

OpenStudy (camerondoherty):

thats it for sure

OpenStudy (anonymous):

OpenStudy (camerondoherty):
