Answer:
Shane could have collected more than 911 Cans
Step-by-step explanation:
We are asked to write an inequality to find the number of cans, S that Shane could have collected:
Cans collected by Shane and Abha > 2000
S + A > 2000
Abha collected 178 more cans than Shane did.
A = 178 + S
Put value of A in the above inequality
S + 178 + S > 2000
2S + 178 > 2000
2S > 2000 - 178
2S > 1822
S > 911

In both cases you may well benefit from graphing the functions.
Do you recognize f(x) = (x + 1)^2 - 1 as a quadratic function, whose graph is that of a parabola that opens up? By comparing this to y = a(x-h)^2 + k, we see that a=1, h= -1 and k = -1. The vertex is at (h,k), which here is the point (-1, -1). This is the minimum value of the function. Thus, the range of this function is [-1, infinity).
Now for the function f(x) = 7x - 11: This is a linear function whose graph is (surprise!) a straight line. When x increases, y increases, without limits to either. Similarly, when x decreases, y decreases.
Thus the range includes all real numbers: (-infinity, infinity).
