Find any points of discontinuity for y=x^2/x^2+1

The function is continuous for all real numbers

Step-by-step explanation:

We have the following function

Note that the denominator of the function is:

This expression is different from zero for all real numbers, since for then , there is no number in the real numbers whose square root is equal to -1.

For this reason the function is defined for all real numbers and has no discontinuity.

This function is always positive, continuous and has horizontal asymptote

Observe the attached image

step-by-step explanation: yes

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
