Describe the end behavior of f(x)=3x4fx=3x4

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

Can someone explain to me how to do

What is the point of inflection for the function f(x)=2cos4x on the interval (0, pi/2)
