Which of the following are correct C# statements for this equation?

Given that



a) y = a * x * x * x + 7;

b) y = a * x * x * (x + 7);

c) y = (a * x) * x * (x + 7);

d) y = (a * x) * x * x + 7;

e) y = a * (x * x * x) + 7;

f) y = a * x * (x * x + 7);

a) y = a * x * x * x + 7;
d) y = (a * x) * x * x + 7;
e) y = a * (x * x * x) + 7;
