Answer:
b. (3,3)
Step-by-step explanation:
Assuming she set up the problem vertically, she began subtracting from the left, instead if the right.
The graph of f(x) opens upward
For the values of x < -5 the function is a line with negative slope, for the values of x > - 5 the function is a line with positive slope.
The two lines intercept in the point (-5,-2). That is the vertex of the function; a minimum value. So, all the other points are above the line y = -2.
