Given function

h(x) = 2x - 1

#15 Find the inverse of h(x)

Substitute x with y and h(x) with x and solve for y:

x = 2y - 12y = x + 1y = 1/2x + 1/2

The inverse is:

h⁻¹(x) = 1/2x + 1/2

#16 The graph with both lines is attached.

The x- and y-intercepts of both functions have reversed values.

#17 Table of the inverse function will contain same numbers with swapped domain and range.

Initial look is like this:

x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | | 0 | | 1 | | 2

The rest of the table is filled in by finding the values:

x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | -0.5 | 0 | 0.5 | 1 | 1.5 | 2

The median is 4 and the range is 5 the average should be 4.5

The median is where the middle is so if you count on either side until you get to the middle you have the median. The average is all the numbers added up divided by the number of numbers ( you might want to check me incase I typed it in wrong on my calculator. The range is just the highest- the lowest:)

Graph the function y = 6 – 2x. Click the intercepts to show the coordinates.

Answers

Answer:

Step-by-step explanation:

Let's find and use the intercepts. They speed up graphing of lines.

y-intercept: In y = 6 – 2x, let x = 0. Then y = 6, and the y-intercept is (0, 6).

x-intercept: In y = 6 – 2x, let y = 0. Then 2x = 6, and x = 3. The x-intercept is therefore (3, 0).

Plot these two points and then draw a line through both.

Step-by-step explanation:

First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

Answer:

$24.50

Step-by-step explanation:

10.50 * 2 1/3 = 24.50

EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)

Answers

Answer:

After eight hours 6,561 people will know the rumor.

Step-by-step explanation:

Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:

Hour 0 = 1

Hour 1 = 1 + 2 = 3

Hour 2 = 3 + 2 x 3 = 9

Hour 3 = 9 + 2 x 9 = 27

Hour 4 = 27 + 2 x 27 = 81

Hour 5 = 81 + 2 x 81 = 243

Hour 6 = 243 + 2 x 243 = 729

Hour 7 = 729 + 2 x 729 = 2,187

Hour 8 = 2,187 + 2 x 2,187 = 6,561

Therefore, after eight hours 6,561 people will know the rumor.

a88 = 4 - 435

a88 = -431

So, the 88th term of the arithmetic sequence is -431.
