What is function?
Function is relationship between two sets,
Set is collection of distinct and well defined objects.so A is one set and B is other set
Then Cartesian products of two sets are called relation. Which is shown as A×B
Function is such type of relationship in which set A has 1-1 link with set B
For example A ={a,b,c} and B={1,2,3}
Then A×B={(a,1),(b,2),(c,3)} here {a,b,c} is domain which should not be repeated.
Write the significant figures for the problems given below;
0.000075
890000
0.000075 - 2 significant figures -
Rule: in a number that has a decimal point, the zeros before the first non-zero digit are all non significant. hence the five zeros before 7 are not significant.
890000 - 2 significant figures
Rule: In a number without an explicit decimal point (i.e., integers) the zeros that follow the last non zero digit are all non significant. hence the four zeros that follow 9 are not significant.
BONUS:
0.00007500 - this has four significant figures. Even though the five zeros before 7 are not significant, the two zeros after 5 are significant.
RULE: in a number that has a decimal point, all the zeros that follow the last non-zero digit are significant.
