ohaa [14]

Answer:

Option C

Step-by-step explanation:

We can easily see the solution by realizing that the quadratic function

y = x^2 + 2 has a discontinuity at x =1 (white dot at the graph)

So, the solution must have

y = x^2 + 2  , x < 1

And the only option in which this applies is Option C.

How many words is a page of double spaced 12 point?
ivann1987 [24]
It also depends on the size of the margin and the font style.

However, assuming that you have a one-inch margin with an Arial font of 12, you'll get approximately 250 words in all.

A study of an international institution however concluded that a double spaced essay with a font size of 12 has exactly 275 words, which is mostly accepted today as a basis.
