Start with f(x) Then scale it by 3 (ie stretch it by a factor of 3) to get y = 3f(x) Now reflect the last graph over the y-axis to get y = 3f(-x)

OpenStudy (anonymous):

ok i understand, but how would you graph f(x) and the stretch factor? thanks so much :)

jimthompson5910 (jim_thompson5910):

Are you given a graph or a function for f(x)?

jimthompson5910 (jim_thompson5910):

By "vertical stretch" I mean change each y coordinate and make them 3 times bigger

OpenStudy (anonymous):

ohhh ok! yay thanks!
