Correct

Question 1.2

Because of the square root, the radicand is restricted to vljafyOhvFRb2cl8x7zWAf3oW8cIpGW6B61AEnHWW1ifKuVd6zt3zwgyD12RrF/HN2wsNcrWAeMr3tEj7hA8VllNcquvi1g26xjrnLOYgaLmN7z/i9fd2GUix5vlOV0T7/xR1w==.

Question 1.6

The only values a square root can produce are AWXjrcRpytWnSE3JwDODssGJj9lchLAeTzudD3x7GJ1KRYP0wFRs7w==.

2
Correct.
Incorrect.

Question 1.7

Write this statement as an inequality for the given function g.

1Wh3cvJ2xF4=

2
Correct.
Incorrect.

Question 1.8

Substituting values fo the domain, t ≤ $a, into verifies the smallest value of the range is g(t) = 1Wh3cvJ2xF4=.

2
Correct.
Incorrect.

1.5 Step 4

Question 1.9

Thus, the range of the function y=g(t) in interval notation is [ 1Wh3cvJ2xF4= , 3LecBr2w/JA= ) or in set notation R:{y: y ≥ 1Wh3cvJ2xF4=}.

(Type "inf" or "-inf" for ∞ or -∞)
