We know that
The
MIN function is <span>a Statistical </span><span>Function that </span>returns the smallest numeric value in a range of values
see the attached table to better understand the problem
the answer isthe option C) Min
Factor x^2+ 4x - 5:-
= ( x + 5)(x - 1)
so we have (x + 5)(x - 1) / -(x - 1)
so answer is -(x + 5) or it can be written as -x - 5.
Number 2) 3/5 is the answer because when both 6 is divided by 2 it is three and when 10 is divided by 2 it is five.
