f(x)= -x^2 + x^-1
f(-2)= - (-2)^2 + (-2)^-1 = -4 - 1/2 = -9/2
f(-1)= - (-1)^2 + (-1)^-1 = -1 -1 = -2
f(1) = - (1)^2 + (1)^-1 = -1 +1 = 0
The range is { -9/2, -2, 0}
Try this explanation+solution:
1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.

Answer:
5.39 units
Step-by-step explanation:
Pythagorean theorem: 
Let point (-2,1) be C
Line segment AC would be 2 units long.
Line segment BC would be 5 units long.
Insert the length of the line segments in to the Pythagorean theorem
4 + 25 = 29
≅ 5.385
