why it says "could not find function 'mutate'"

hi friends, im learning R recently and I have this problem with it. I tried to add a new column with mutate but it says "could not find function 'mutate'" I do not understand why. Do I need to install extra packages? Could somebody please help me out? Thank you!

> Age<-mutate(NobelNew,age=YOA-YOB)
Error in mutate(NobelNew, age = YOA - YOB) : 
  could not find function "mutate"

yes, you should one time install tidyverse
