Transformations of Functions (A1) The graph of y=f(x) is the solid black graph below. Which function represents the dotted graph?

A: y=f(x−1)−1

B: y=f(x−1)+1

C: y=f(x+1)+1

D: y=f(x+1)−1

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
