Question

could someone tell me how to graph this?
y=3 f(-x)

Answer 1

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)

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

ohhh ok! yay thanks!
