f(x) = x2 + 4 and f-1(x) = -vx4
when comparing the functions using the equations, which conclusion can be made?
the domain of f(x) is restricted to x 20, and the domain of f'(x) is restricted to x 20.
the domain of f(x) is restricted to x 0, and the domain off'(x) is restricted to xso.
the domain of f(x) is restricted to x s 0, and the domain off'(x) is restricted to x2 4.
the domain of f(x) is restricted to xs 0, and the domain off'(x) is restricted to x 54.

(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
