Find the center and radius of each.

1 answer:

7 0

x^2+y^2=49

Radius 7
Center (0,0)

x^2+y^2=324

Radius 18
Center (0,0)

x^2+(y+2)^2=121

Radius 11
Center (0, -2)

(x+10)^2+(y+9)^2=8

Radius 2√2≈2.82843
Center (-10, -9)

Answer:

f^-1(x) = (x +4)/3

Step-by-step explanation:

The inverse function is found by swapping x and y, then solving for y.

y = 3x -4 . . . . . function y = f(x)

x = 3y -4 . . . . . inverse relation

x +4 = 3y . . . . add 4

(x +4)/3 = y . . . divide by 3. This is the inverse function

f^-1(x) = (x +4)/3
