Which statement describes the graph of f(x) – Lx}-2 on [0, 3)? The steps are at y = -2 for 0 sx<1, at y = -1 for 1 5x<2, and at y = 0 for 2 O The steps are at y = 0 for 0 5x<1, at y = 1 for 1 Sx <2, and at y = 2 for 2 The steps are at y = 1 for 0 sx<1, at y = 2 for 1 sx <2, and at y = 3 for 2 Sx <3.
The steps are at y = -3 for 0 Mark this and return
So

X^-2  - 2x^-1 - 8 = 0

(1/x²) - (2/x) - 8 = 0
(1-2x)/ x²  = 8
1-2x = 8x²
8x²+2x-1 = 0
(4x - 1) (2x + 1) = 0
x=1/4   ,   x=-1/2
