Shannon is traveling from New York City to Washington, D. C. She wants to go by train so she can see the views. Since she will be driving home with a family member, she only priced the cost of a one-way ticket on Amtrak for any time of day on February 15. Below is an ordered listing of all fares that were available for selection on that day. Find the percentile rank for a fare of $119. fill in the blank 1 Find the percentile rank for a fare of $272. fill in the blank 2

Based on your first two answers, which train fare would have a percentile rank of approximately 82%?

f(x)= 4x + 1 is written in function notation and is read “f of x equals 4x plus 1. ... B) 3x = y – 2 and f(x) = 3x – 2 ... Given f(x) = 3x2 + 2x + 1, find f(0), f(2), and f(−1).

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

f(x)=2/3x-8, which give g(x) the greatest value.
