Consider the following claim: If the point (2 +d, y) is on the graph of the function f(x) = x(x - 4), then the point (2-d, y) is also on the graph. • Use algebra to show that the claim is true.
• What is the relationship between the line x = 2 and the graph of f(x)? Justify your reasoning,
Enter your work, your answer, and your justification in the box provided.

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?
