Question

find the domain and range of f(x)=sq.100-x^2

Answer 1

so (100)^(1/2) - x^2 if so: D{x is Real) R:{y| y is Real, y <= 10)

if (100-x^2)^(1/2) D: {x| x is Real, x < 10^(1/2)} R: {y| y is Real, y >=0}

Answer 2

so how would I write it?

Answer 3

what is the domain
and the range how do I write it?
