Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x - 6|?. . . shift 6 units up. s
s2008m [1.1K]

Answer:

Shift 6 units right.

Step-by-step explanation:

Easiest way to answer this question is to plot the two graphs:

Let's plot these graphs and analyse each graph.

Lets take the graph of y=|x| that is attached.

We can clearly see that graph intersects x axis at x=0 and then essentially looks like y=x is mirrored by the y axis.

Now when we look at the y=|x-6| that is attached,

We can see that graph intersects x axis at x=6 and is a composite graph of y=|x-6| and its mirrored graph by y=6.

We can clearly see that graph has moved 6 units to the right.

Show that f(x)=πx-2 and f-1(x)=(x+2/π) are inverse functions of one another
iVinArrow [24]
They are not inverse functions of one another. For f(x) and g(x) to be inverses of each other, f(g(x)) = x. In this case, pi(x+2/pi)-2 = pi* x, which is not x.
