Practice problem
What is the range of the function y=x2+1y = x^2 + 1y=x2+1?
(−∞,∞)(-\infty,\infty)(−∞,∞) (all reals)
[1,∞)[1,\infty)[1,∞) (reals greater than or equal to 111)
[0,∞)[0, \infty)[0,∞) (reals greater than or equal to 000)
[−1,∞)[-1,\infty)[−1,∞) (reals greater than or equal to −1-1−1)
Type a concept, like “slope” or “photosynthesis”.
