ok , here is the question:

1) Does this function's graph intersect its horizontal asymptote?

g(x) = x / x ² + 1

2) Does this function's graph have more than one horizontal asymptote?

g(x) = | x - 1 | / x² - 4

3) Prove that the graph of every odd function with domain all real numbers must pas through the origin.

4) Show algebraically that -1 < 3x² - 1 / 2x² + 1 < 1.5


any help at all is appreciated, ~! thanks a lot~!! ^-^

A particle moves along the x-axis in such a way that its position at time t greater than or equal to 0 is given by
x = (1/3) (t^3) - 3t^2 + 8t.

(a) Show that at time t = 0 the particle is moving to the right.

(b) Find all values of t for which the particle is moving to the left.

(c) What is the position of the particle at time t = 3?
ok is this part just asking for what (t,x) is when t=3?

(d) When t = 3, what is the total distance the particle has traveled?
ok so is this part asking for the distance between (0,0) and the answer from part (t,x) when t=3?
