Set P U (R U O) set P= {1,3,5,7,9,11,13...21} Set R= {2,4,6,8,10,12} Set O= {3,6,9,12,15,18}

sorry I don't know the answer

Step-by-step explanation:

P= {1,3,5,7,9,11,13,21}

R ={2,4,6,8,10,12}

O={3,6,9,12,15,18}

The union of two sets contain all the elements in  either set.

R ∪ O = {2,4,6,8,10,12,3,9,15,18 }      [6 & 12 are in both R and O. we have to write only one time]

P U (R ∪ O) = {1,3,5,7,9,11,13,21,2,4,6,8,10,12,15,18}

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
