What is the equation for the line of symmetry for the graph of the function y = - 4x^2 + 6x - 8

Y = - 4 x² + 6 x - 8

This is the quadratic equation in the standard form:

y = a x² + b x + c,

where: a = - 4, b = 6, c = - 8.

x = - b / 2 a = ( - 6) / ( - 8) = 3/4 = 0.75

Answer:

The equation for the line of symmetry for the graph of the function is x = 0.75.
