CAN SOMEONE HELP ME WITH THIS PROBLEM WHAT IS THE RANGE FOR THE FUNTION GRAPED AS SHOWN? Y=2X2+4X DON'T UNDERSTAND IT...
Answered by bobpursley
if the domain of x is from -inf to + inf, then the range y=2x(x+2) is from zero to inf.

Notice when x is very large negative, then y= large negative *(negative) =positive.
