Question

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

- The domain is all real numbers
-the y intercept is 3

Answer 1

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.
