Question 1179075: Graph f as a solid line and f-1 as a dashed line in the same rectangular
coordinate space. Use interval notation to give the domain and range of f
and f-1.
f(x) = x2 - 5, x ≥ 0

f%28x%29=x%5E2-5, x ≥ 0, domain [0,∞), range [-5,∞)
y=x%5E2-5
x=y%5E2-5
x%2B5=y%5E2
sqrt%28x%2B5%29=y
f-1(x) = sqrt%28x%2B5%29, x ≥ -5, domain [-5,∞), range [0,∞)
