Question

how to solve f(x)=x^2-3x-2

Answer 1

will u elaborate

Answer 2

there is nothing to solve

Answer 3

you may solve x^2-3x-2=0

or you may find the zeros of f(x)

but solving f(x) makes no sense.

Answer 4

given the function rule f(x)= x^2 -3x+2, what is the out put of f(-2)

Answer 5

12

Answer 6

i need to know how did u do it

Answer 7

not the awenser

Answer 8

put a -2 where you see an x

\(f(x) = x^2-3x-2\\f(-2) = (-2)^2-3(-2)-2 = 4+6-2=8\)

Answer 9

THANK YOU SO MUCH!!!!

Answer 10

-2^2 -3(-2)+2=12 @zzr0ck3r

Answer 11

its not -2^2 its (-2)^2

Answer 12

-2*-2 = 4

Answer 13

one must be careful when plugging in cvalues, I always use the () as I did ablove as not to confuse myself...

Answer 14

values*

Answer 18

given the function rule f(x)= x^2 -3x+2, what is the out put of f(-2) @zzr0ck3r

Answer 19

I am right. I promise

Answer 20

i know for a fackt that the awense is 12 but i dont know how to work it out

Answer 21

fact*

Answer 22

that topic says -2

Answer 23

f(x)=x^2-3x-2

Answer 24

I am confused
