Which function has a domain of all real numbers?  A. Y=(x+2)^1/4
B. Y=-2(3x)^1/6
C. Y=(2x) ^1/3-7
D. Y=-x^1/2+5

I'd give A a shot

Step-by-step explanation:

Its domain is x|x>-2, and -2 is a real number

EMERGENCY CORRECTION: THIS IS WRONG AND I'M TOO ST*PID TO FIGURE OUT THE REAL ANSWER I'M SORRY

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
