Consider the function and its inverse. f(x) = x ^ 2 + 4 and f ^ - 1 * (x) = - sqrt(x - 4) When comparing the functions using the equations, which conclusion can be made? OThe domain of f(x) is restricted to x >= 0 , and the domain of f ^ - 1 * (x) is restricted to x >= 0 . The domain of f(x) is restricted to x >= 0 , and the domain of f ^ - 1 * (x) is restricted to x <= 0 . The domain of f(x) is restricted to x <= 0 , and the domain of f ^ 1 * (x) is restricted to x >= 4 . The domain of f(x) is restricted to x <= 0 , and the domain off f ^ - 1 * (x) is restricted to x <= 4 .

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
