Practice problem
What is the range of the function x2+1+1\sqrt{x^2 + 1} + 1x2+1+1, given that the domain is all real numbers?
[0,∞)[0, \infty)[0,∞)
(0,∞)(0, \infty)(0,∞)
[1,∞)[1, \infty)[1,∞)
(1,∞)(1, \infty)(1,∞)
[2,∞)[2, \infty)[2,∞)
(2,∞)(2, \infty)(2,∞)
Type a concept, like “slope” or “photosynthesis”.
