Which equation could be the equation of this parabola?

a. y = -2x^2

b. x = -2y^2

c. x = 2y^2

d. y = 2x^2

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

If f(x)= 3x+6 which of the following is the inverse of f(x)

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1
