The answer is D as it can be rewritten as -((y^2)/5)-(8/5)=x. Solving for the x-intercepts you get -((y^2)/5)-(8/5) = 0 as you want to find the y values when x is zero. Solving for y you get: (y^2)/5)+(8/5) = 0 => (y^2)/5)=-(8/5) => y^2=-8 => y = plus or minus sqrt(-8). The first problem is that you have 2 x intercepts which already makes it not a function and second sqrt(-8) is an imaginary number making the solution not a real number.
Answer:

Step-by-step explanation:
The radical
can be simplified by breaking it down into factors and removing the perfect squares from inside the radical.

25 is a perfect square and is 5 outside the radical.
is a perfect square and is x outside the radical.
is a perfect square and is
outside the radical.
