First, graph each point on the coordinate plane.
Now think of a vertical line moving from left to right. The line is always vertical. It starts at the left of the graph and moves to the right. If at any time, the line intersects more than one point, then the relation is not a function. If all the x-coordinates are different, the vertical line cannot touch more than one point at a time.

Consider these four functions. Choose the one which will be the greatest as x → ∞. A) h(x) = 3x B) f(x) = x25 C) g(x) = 5x500 D)
Nikolay [14]
For this case what you should know is that all functions tend to infinity when x tends to infinity.
 However, there are functions that grow faster than others.
 In this case, the function that grows fastest is the one with the highest exponent.
 We have then:
 g (x) = 5x ^ 500
 The exponent of 500 makes the function grow to infinity faster than the other functions.
 Answer:
 C) g (x) = 5x500

Mr. Taylor filled out a bracket for the NCAA National Tournament. Based on his knowledge of college basketball, he has a 0.54 pr
boyakko [2]

Answer:

The probability is 2.7327 \times 10^{-9}

Step-by-step explanation:

The probability of guessing correctly, P = 0.54

Probability of not guessing correctly, q = 1 – P  

q = 1 – 0.54 = 0.46

Number of trials, n = 32

Now calculate the probability that Mr. Taylor will pick 32 correctly in first round of the game.

Below is the calculation using binomial distribution.

Probability = \left ( _{k}^{n}\textrm{} \right )P^{k}(1-P)^{(n-k)} \\= \left ( _{32}^{32}\textrm{} \right )0.54^{32}(0.46)^{(32-32)} \\= 0.54^{32} \\= 2.7327 \times 10^{-9}
