If f(x)=x-3/x
and g(x) = 5x – 4, what is the domain of (fºg)(x)?

The domain is all real numbers except x=4/5

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
