The domain is the set of feasible inputs, i.e. the x-coordinates in which you can evaluate the function.
We can see that this function is defined only for x values between -1 and 3 (included), so this is your domain.
Answer:
B is the answer
Step-by-step explanation:
Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.
Plug 17 into both to find the smaller angle
So 33 is the answer or B
Answer:
7x² + x – 2
Step-by-step explanation:
(4x² + 3) – (–3x² – x + 5)
First, distribute the minus sign to eliminate the parentheses (negative terms become positive and vice versa):
4x² + 3 + 3x² + x – 5
Then, combine like terms:
7x² + x – 2
