Transformations Flashcards
1
Q
y = f(x) + a
A
plus a - up
minus a - down
2
Q
y = f(x-a)
A
plus a - left
minus a - right
3
Q
y = -f(x)
A
Reflection in x-axis (y coordinates inverse)
4
Q
y = f(-x)
A
Reflection in y-axis (x coordinates inverse)
5
Q
y = kf(x)
A
Stretch in y-axis
Scale factor k
(x values remain the same, y values multiplied by k)
6
Q
y = f(kx)
A
Stretch in x-axis
Scale factor 1/k
(y values remain the same, x values multiplied by 1/k)
