Consider the quadratic function
f (x )= ax^2 + c , a ≠0.

If a > ​0, then f has a minimum that occurs at x = . This minimum value is​ .
If a < ​0, then f has a maximum that occurs at x=. This maximum value is​ .

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′.
