Transformations And Bearings

Question 1

What are the 4 transformations?

Answer 1

• translation
• reflection
• rotation
• enlargement

Question 2

How do you find the roots?

Answer 2

Factorise (into two brackets)

Question 3

How do you find turning point?

Answer 3

Complete the square

Question 4

With vectors, what do the two values mean?

Answer 4

One on top is x (left/right)

One on bottom is y (up/down)

Question 5

With transformations, when ‘a’ is inside the brackets which axis is involved?

Answer 5

X-axis

Question 6

With transformations, when ‘a’ is outside the brackets which axis is involved?

Answer 6

Y-axis

Question 7

y = f(x+a)

Answer 7

Translation (-a, 0)

along x-axis

Question 8

y = f(x) + a

Answer 8

Translation (0, a)

along y-axis

Question 9

y = a f(x)

Answer 9

Enlargement on/in y-axis

scale factor of a

y = f(ax)

Answer 10

Enlargement in x-axis

scale factor of 1/a

y = f(-x)

Answer 11

Reflection in y-axis

y = -f(x)

Answer 12

Reflection in x-axis
