Question

Can someome explain this please?
Given the equation y=x^n where x>0 and n<0, which statement is valid for real values of y?
A) y>0
B) y=0
C)y<0
D)y greater than or equal to 0

Answer 1

Y will always be greater than zero. It could never be zero. Your graph goes from very large, to extremely small. So long as that 'X'>0, an exponent 'N' can force 'Y' to be negative.
