Which pair of functions satisfies(f∘f−1)(x)=x and (f−1∘f)(x)=x? f(x)=x+3−−−−−√3 and f−1(x)=x3−3

f(x)=x+7−−−−−√, x≥−7, and f−1(x)=x+7

f(x)=x2+1 and f−1(x)=x+1−−−−−√, x≥−1

f(x)=x3+5 and f−1(x)=x−5−−−−−√, x≥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.

the correct answer is $7.38
