How does a transformation affect the graph of f(x) if it is changed to:

1 answer:

4 0

If you add a value to the outcome of the function (as in case a), you will just shift the graph up along the y-axis. Makes sense, right, since you're adding an extra 2 to the value you will plot on the y axis.

If you subtract (in this example) a value to the input of the function, you're actually "looking back" into the past of the graph (i.e., the left side). For example, for x=4 you're now plotting the value that used to be at x=1. So this shifts the graph to the right.

That may be confusing at first. But I hope with a little thought experiment, you get it.

Given that a randomly chosen flight arrives on time, what is the probability that it arrives in Philadelphia (PHL)?

olga55 [171]

Using concepts of probability, it is found that there is a 4.7% probability that it arrives in Philadelphia (PHL).

<h3>What is a probability?</h3>

A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Over a large number of trials, a percentage can also represent the probability of single event.

In this question, researching the problem on the internet, we have that over a large number of flights, of those which arrived on time, 4.7% of them were in Philadelphia, hence:
