If the local maximum of y=f(x) occurs at (4,15), where would the local maximum occur on y=3f(x+2)?
Can you help me?
the +2 shifts the graph to the left by 2.
so if the max was at (4,15) now it will be at (2,15)
the multiplication by 3 merely makes the max three times higher. so if it is at (2,15) for f(x+2) for 3f(x+2) it will be (2,45)
