Part 1 of 2
Without sketching the graph, how can you identify the domain and range of f(x)=4-√2x-5?
How can you identify the domain? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
OA. The radicand must be negative, so the domain is
(Type an inequality or a compound inequality.)
OB. The radicand must be positive, so the domain is
(Type an inequality or a compound inequality.)
TEREN
OC. The radicand must be nonnegative, so the domain is
(Type an inequality or a compound inequality.)
OD. The domain is all real numbers for all functions.
O E. The radicand is always negative, so the domain is the empty set
