Which are characteristics of the graph of the function f(x) = (x + 1)2 + 22 Check all that apply.
Sunny_sXe [5.5K]

Answer: The domain is all real numbers

I can't say that the y intercept is 3 because when you distribute,

f(x) = (x + 1)2 + 22 \\ f(x) = 2x + 2 + 22 \\ f(x) = 2x + 24

It seems like the y intercept is 24.

Can someone help me please? Maybe give the answers?<br><br><br><br><br><br>Thank you.
pishuonlain [190]

Answer:

Finding the missing number is fairly simple and can be done in a few short steps. I will show you using the 21 / __ fraction.

First, divide the included number by its corresponding number in the original fraction.

21 ÷ 3 = 7

To find what the denominator of this would be, multiply 4 by 7.

4 * 7 = 28

The fraction would be 21 / 28.

This works with both numerators and denominators. If you need more of the answers just ask in the comments.
