50=16t^2
Divide both sides by 16
3.125=t^2
Find the square root of both sides (approximated)
1.77= t
Final answer: F

Answer:
Domain:![[-1,0]\cup [1,\infty )](https://tex.z-dn.net/?f=%5B-1%2C0%5D%5Ccup%20%5B1%2C%5Cinfty%20%29)
Step-by-step explanation:
Since we know that a square root function is not defined for negative numbers. In order our function to be defined values inside radical must be greater than or equal to zero.
Our function will be defined when


or 
Now we will use number line method of solving inequalities to check whether our answer is right or not.
Let us try -2, -1/2, 1/2 and 2 to check which conditions meet our criteria.






Therefore, we can see that our function is defined when
or
and domain of f(x) is
.
