How is the domain of a trigonometric function restricted so that its inverse function is defined?

FILL IN THE BLANKS

The graph of f(x)=tan(x) .

a. is one-to-one

b. does not pass the horizontal line test

c. does not pass the vertical line test

Therefore, a domain restriction must be placed on the function for the inverse function to be defined. The domain restriction placed on f(x)=tan(x) is so that its inverse function is defined.

a. (-pi/2, pi/2)

b. (0, pi/2)

c. (0, pi)

d. [-pi/2, pi/2]

e. [0, pi/2]

f. [0, pi]

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
