Question

Describe how y=f(x) is transformed by
a)y= -f(x+2)-5
b)y=f(-x)+5

Answer 1

a) well adding something to x will move it to the right along the x-axis; subtracting 5 will move it down 5 along the y-axis; multiplying the whole thing by -1 will reflect it about the x-axis

Answer 2

b) multiplying x by -1 will reflect it about the y-axis; adding 5 will shift it up 5 units along the y-axis

Answer 3

Try to visualize the lines on a graph so you can learn to just "see" this by looking @ the equation. Break it into components.
