Answer:
(^6√x^5) (√y)
(The 6 belongs in the left on top of the square root btw)
For x the 6 moves to the front of the square root while the 5 becomes the power of x.
For y, the power to the 1/2 is the same as a square root.
It is not straight and does not always pass through 0,0
so A, C, and D are incorrect.
Look up nonlinear function, and it shows a curved line.
The answer is B. It can be curved.
C) 2x^2 + 3/2x - 5
Just add the two functions.
