Hello!
(Image attached is to help with finding places needed to round. made by me on google docs)
Rounding is just something you need to get the hang of to know.
If the number to the right of the place you are rounding in is 5, 6, 7, 8, or 9, remove it and everything to the right, then add 1 to the number to the place you are rounding in
if the number is 4, 3, 2, 1, or 0, remove it and everything to the right, then keep the number in the place you are rounding in the same.
in this case, the tenths place holds a 7. The number to the right of it is 4. therefore, you remove the 456, and leave the 7 as-is
your final answer is 0.7.
in fraction form,
and in percent form, 70%
I hope this helps, and have a nice day!

Answer:
x ≥ -1/2
Step-by-step explanation:
We know that we cannot graph imaginary numbers. Therefore, our <em>x </em>value has to be greater than or equal to 0:
To find our domain, we need to set the square root equal to zero:
√(4x + 2) = 0
4x + 2 = 0
4x = -2
x = -1/2
We now know that no value below -1/2 can be used or we will get an imaginary number. Therefore, our answer is x ≥ -1/2
Alternatively, we can graph the function and analyze domain:
