The domain of a function is where the x of the function starts and finishes , but as that function doenst have an end or beginning, its domain is a) from negative infinity to infinity
Taking the square root of both sides gives two possible cases,
or
Recall that
If 
and 
, we have
so in the equations above, we can write
Then in the first case,
(where 
is any integer)
and in the second,
Then the solutions that fall in the interval 
are
Answer:
Hyperbola
Step-by-step explanation:
Its just like a parabola, but with 2 equal cones making them on opposite sides.
-3*-5 = 15
<span>When the signs are the same the answer is positive.</span>
STEP BY STEP EXPLANATION
(Mark brainliest pls)
Square root is 2 square + 4 square + 1 because 1 does not enable a square perhaps for negatives to be imputed, and we know 2 square will be 1 hence,
1 x 1 = 1 squared
2 x 2 = 4 squared
Perhaps for 1, you will have to use a formula equation and add tang maybe. Etc I don’t know if tang but u will also have to convert 1 to a decimal to find the square root of 1, 1 is an odd number so it will end up with remainder decimals or just do 1x1, etc.
Hence u
(2 square + 4 square) + 1square?
It depends on addition or order of operations subtraction addition or you will might use multiply
if the subject is about multiply or Division so try and do it because i don’t know if I’m right
..
REMEMBER
PEMDAS
Please Excuse My Dear Aunt Sally

try and solve it hope this helps!
Have a nice day
