Guide to Transforming graphs y=f(x): Explanation, Diagrams & Worked Examples

Download Printable One Page Guide (PDF)

Explanation:

Changes outside the bracket affect the y-coordinates as expected, whereas changes inside the bracket affect the x-coordinates in the opposite direction:

• y = f(x) + a translates by vector 0a (up by a);  y = f(x + a) translates by vector −a0 (left by a).
• y = −f(x) reflects in the x-axis (y changes sign);  y = f(−x) reflects in the y-axis (x changes sign).

Example 1: The curve y = f(x) has a turning point at P(3, −4). Find the coordinates of the turning point on: (a) y = f(x − 2) + 5  (b) y = −f(x).

f(x) P(3, −4) −f(x) (3, 4) (5, 1) f(x−2)+5

Solution:

(a) Inside (x − 2) shifts right by 2: x = 3 + 2 = 5
Outside (+ 5) shifts up by 5: y = −4 + 5 = 1 ⇒ (5, 1)
(b) y = −f(x) reflects in the x-axis (multiply y by −1):
Answer: (a) (5, 1)   (b) (3, 4)

Example 2: Given f(x) = x2 − 4x, find the equation of the curve after a reflection in the y-axis followed by a translation of 0−3.

Solution:

Reflection in y-axis replaces x with −x:
f(−x) = (−x)2 − 4(−x) = x2 + 4x
Translation by 0−3 subtracts 3 from the function:
Answer: y = x2 + 4x − 3
