ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2

If the diameter of this circle is .96, then the radius is .48. The h and k values of our center are (-2, 5), and the standard form of a circle is

. We will fill in accordingly.

. That simplifies to

. That's the equation of the circle that will completely enclose the quarter.
