Question

Please help
Graph the function. State its domain and range.
y=3 x e(^-x) - 2

Answer 1

e^(-x) would never become a negative value regardless what the value of x is, just become very small to value of zero or to infinity. so the range is -2 to infinity. While the domain. while the equation is always valid for watever the x is so i think the domain is infinity
