Answer:
sum = -15h+2
Step-by-step explanation:
The other endpoint would have to be (-5,2), going off the definition of a midpoint. Since 3 is for units to the right of -1, that would mean that the other end point would have to be 4 units to the left, which is -5.
The correct answer would be A), because the two shortest sides should be greater than the longest side when added together.
It's a cubic with a positive x^3 coefficient. The general shape is "/".
It goes to -∞ for large negative x.
It goes to +∞ for large positive x.
