Since it’s 25 m ever 1/6 hour, it’s 150 m every hour, so it’s 300 m in two hours
Given that the surface area of the sphere is S(x)=4πx², the inverse function will be obtain as follows: make x the subject of the function
S(x)/(4π)=x²
get the square root of both sides:
x=√[S(x)/(4π)]
replace x by S⁻¹(x) and S(x) by x
this will give us the inverse as :
S⁻¹(x)=√[x/(4π)]
The above implies that the inverse is the square root of the radius divided by 4π
Answer:
B)All the real numbers
Step-by-step explanation:
the given Graph is Parabola
so the function has to be quadratic
we know that the domain of a quadratic function is always 
hence, our answer is B
