Which of the following functions best describes this graph?

Mathematics
1 answer:
Katarina [22]2 years ago
4 0

We see that the zeros of the function are 4 and 5.

Now lets us write that into the equation

    y=(x-4)(x-5)

Now multiply that out

    y = x^2-5x-4x + 20 = x^2-9x+20

Hope that helped!

According to the bar graph above, which salary range is the least frequent?
Elis [28]

9514 1404 393

Answer:

  D.  $101,000 – $120,000

Step-by-step explanation:

The bar graph is not completely labeled, but in the context of the question it seems safe to assume that the vertical scale can be considered to represent relative frequency.

So, the shortest bar is the one with the lowest frequency. The horizontal scale identifies that as 101-120. If we assume that is salary in thousands of dollars, then Choice D is appropriate.
