Write the equation of a circle with a center at (-3,-4) and a radius of 3?

Answer 1

Claire Akin

The equation of a circle with center #(x_o,y_o)# and radius #r# is

#(x-x_o)^2+(y-y_o)^2=r^2#

hence in our case

#(x+3)^2+(y+4)^2=3^2#

The equation of a circle with a center at (-3, -4) and a radius of 3 is:

[ (x + 3)^2 + (y + 4)^2 = 3^2 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
