Here are all the steps, and what they do:
STEP 1: HORIZONTAL TRANSLATION
We transform
The general transformation is
These transformations translate the graph horizontally, k units to the left if k>0, k units to the right if k<0.
In this case, k = -1, so we translate the original graph 1 unit to the right.
STEP 2: VERTICAL STRETCH
We transform
The general transformation is
These transformations stretch the graph vertically. The graph expands if |k|>1, while it shrinks if 0<|k|<1. If k is negative, we also reflect the graph with respect to the x axis.
In this case, k = 3, so we stretch the graph vertically by a factor 3.
STEP 3: VERTICAL TRANSLATION
We transform
The general transformation is
These transformations translate the graph vertically, k units up if k>0, k units down if k<0.
In this case, k = 4, so we translate the graph 4 units up.
So, we start from the original graph of and we:
- Translate it 1 unit to the right
- Stretch it vertically by a factor 3
- Translate it 4 units up
(the order is important!)

Let's start with 22-C!
To figure out the problem, let's establish what it's asking. It wants to know the one time fee of using the trash dumpster. Your teacher may have taught you a better way to do this, but I'll show you how to solve it via logic.
We first need to set up a basic equation. X will be the unknown fee, 195 will act as the total, and 9(15) will represent the remaining cash (you get this from 15$ an hour for 9 hours).
The equation should look something like this:
x + 9(15) = 195 OR (simplified) x + 135 = 195.
At this point we can solve it like a regular equation. Subtract 135 on both sides:
x = 60. Therefore, the fee for using the dumpster is 60$.
Now we can move on to 23-A & B!
First, let's go over 2 basics: point slope formula and slope intercept.
Point slope formula: <em>y - y</em>
Slope intercept: <em>y = mx + b</em>
We know that .5 is the slope because it's dependent on an amount of time (or dependent in general). 64 can be used as y1 and 48 as x1.
The formula would be: y - 64 = .5(x - 48).
As for part B, we plug in the same numbers! We've previously found that .5 is the slope (m) and it appears you already know that the y-intercept (b) is 40. Plug it in like so:
y = .5x + 40
All of the answers are bolded, I hope this helped!
Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:
In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:
