Given: f(x) = 3x ^2 + 1, g(x) = 2x - 3, h(x) = x

h -1 (x) =

x
1/x
-x

Since it's H^-1(x), than just look at the H(x)=x section and do the following:

1) Substitute the x in the equation for the x from the H^-1(x) -

  H(x)= (x)

2) Next take the x out of the parentheses cause there's nothing to multiply it to:

   H(x)= x

3) x is your answer cause there's nothing else to do

x

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

the correct answers are 1, 2, 4, and 5! i just got it right!
