What are the solutions to 4x^2 +25=0

Average acceleration: i have no idea how to do this.

Given the graphed function below which of the following orders pairs are found on the inverse function

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
