For each of the following sets use english to describe the set and when appropiate use roster method to specify all of the elemts of the set.
ONLY C & F
Solution
In roster or tabular method we represent a set by directly listing all of its elements, which are separated by commas and enclosed by a pair of curly brackets.
SOLUTION OF (c)-
In this part x is the set of elements for which equality x^2=16 holds true
so solving the equality x^2=16 would give us-
x= Sqrt (16)
x= 4,-4
so set x = {4,-4} is our answer.
SOLUTION OF (c)-
In this part x is the set of elements for which inequality 3x-4>17 holds true
Solving the inequality 3x-4>17
3x>17+4
x>21/3
x>7
So it indicates that x holds true for all values of x greater than or equal to 7.
x = {7,8,9,10,11,12,13,14,15,...}
The ellipsis (the three periods in a row) means \"and so forth\", and indicates that the pattern continues indefinitely in the given direction.
