Question

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

if F(x)= -2, what is X

Answer 1

F(x) = -2 when x = 0. Setting x=0 gives the y-intercept for the graph of f(x).

Answer 2

is there another answer besides zero?

Answer 3

lol just plug in ur point as y :)
-2=3x^2 - x - 2

Answer 4

can u do it or do u want the answer and for Tims, y-intercept does not equal solution

Answer 5

x=0 and x=1/3 :)

Answer 6

well, i see zero is an answer after plugging in, but apparently there is another answer that = -2 as well. and i cant find it

Answer 7

its 1/3 newkidoncampus :P

Answer 8

haha. ok i tried 1/2 but not 1/3. thank you.

Answer 9

-2=3x^2 - x - 2
0=3x^2-x
0=x(3x-1)
x=0 and 3x-1=0 x=1/3 :)

Answer 10

this is how u do it :)

Answer 11

ohh ok. got it. ;)
