From what I know this graph looks like that of a modulus function except it's shifted 1 unit to right and 1 unit below the origin.

So the original equation must be:
y = |x|

And the transformed equation (aka the equation if this graph) must be,

y+1 = |x| -1

y = |x| -2

What is the value of the function at x=−2?

So for this problem, the x-axis is the horizontal line in the center.

Go to where -2 is on the x-axis as shown. Use your finger to trace along since that's usually helpful in finding the point.

Move your finger from -2 on the x-axis to where the solid black line is. On the right side of that, you can see that the y-axis holds the number 2 which is what the y equals for this solid line.

Therefore, the answer should be c.) y = 2

We have given the 2 by 2 frequency table.

The probability that a randomly selected book is a nonfiction paperback =

(Number of nonfiction paperback books) / Total number of books

= 23 / 69

= 0.3333

The percentage of nonfiction paperback books is 33.33%
