Transformations

Question 1

Y = f(x) + a

Answer 1

Y coordinate + A

Translation along y axis

Question 2

Y = f(x + a)

Answer 2

X coordinate - A

Translation along x axis

Question 3

Y = af(x)

Answer 3

Y coordinate x A
Stretch along y axis
Sf = A

Question 4

y = f(ax)

Answer 4

X coordinate / A
Stretch along x axis
So = x/a

Question 5

Y = -f(x)

Answer 5

Y coordinate x -1

Reflection in X axis

Question 6

Y = f(-x)

Answer 6

X coordinate x -1

Reflection in y axis
