## The Circle New Topic: The Circle

By the end of this topic you will:

• know that the equation of the circle centre (a,b) and radius r is (x – a)² + (y – b)² = r²

• know that x² + y² + 2gx + 2fy + c = 0 represents a circle centre (–g, –f) and
radius r = √(g² + f² – c), provided g² + f² – c > 0

• be able to determine the equation of a circle

• be able to solve problems with the intersection of a line and a circle,
and a tangent to a circle

• be able to determine whether two circles touch each other

## Translating Functions

Desmos Calculator Activity

Explore the effects of changing the vales of a, b, c and d individually.

Discuss and agree the translations:

y = f(x + a)

y = f(x) + b

y = cf(x)

y = f(dx)
