Answer:
Explanation:
You want to know the equation that could describe a graph with x-intercepts at -2 and +1.
Equation
Consider the factored form of the function with x-intercepts of -2 and +1:
y = (x -(-2))(x -(+1))
y = (x +2)(x -1)
Expanding this to standard form gives ...
y = x² +2x -x -2
y = x² +x -2 . . . . . . . . . collect terms. Matches choice C.
