What is the rule for reflection across the y axis

The graph of the quadratic function shown on the left is y = –0.7(x + 3)(x – 4). the roots, or zeros, of the function are . determine the solutions to the related equation 0 = –0.7(x + 3)(x – 4). the solutions to the equation are x =

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
