Answer 1

2.
g(-1) = 1/-1 → -1
f(-1) = (-1)² -1 → 0

(b)

3.
y = (x -1)/x
x = (y -1)/y
xy -y + 1 = 0
y(x -1) = -1
y = -1/(x -1)
f(x)⁻¹ = -1/(x -1)

4.
(-2 , 0)   (0 , 3)
$\left \{ {{0 = -2a + b} \atop {3 = 0a + b}} \right.$
b = 3

-3 = -2a
3/2 = a
f(x) = 3x/2 + 3

f(-1/3) = (-3/3)/2 + 3
f(-1/3) = -1/2 + 3 → 3 - 0,5 → 2,5
