we know that the scale factor produce a contraction when its value must be less than zero
Let SF---------------> scale factor SF< 0------------> produce a contraction A.) 5/2 --------> 2.5 SF>0 not produce a contraction B.) 1.2 --------> 1.2 SF>0 not produce a contraction C.) 2.3 --------> 2.3 SF>0 not produce a contraction D.) 3/4--------> 0.75 SF< 0 produce a contraction
