What is the equation for the axis of symmetry in the function? y = -2x^2 + 5x - 4
like I said in

if (h,k) is the vertex, the axis of symmetry is x = h
So just find the vertex and you got it
answer is x=5/4
correct! good job
To find the equation for the axis of symmetry in a quadratic function, you can use the formula: x = -b / (2a), where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c.
In the given function y = -2x^2 + 5x - 4, we can identify a = -2 and b = 5.
Using the formula, we can find the axis of symmetry as follows:
x = -b / (2a)
x = -5 / (2 * -2)
x = -5 / -4
x = 5/4 or 1.25
Therefore, the equation for the axis of symmetry in the function y = -2x^2 + 5x - 4 is x = 1.25.
