What is the equation for the line of symmetry for the graph of this function? function y = x2 - 4x - 5,
if you have a graphing calulator you can put it in there, or just graph it on a piece of paper using a T chart. find it by one of those.
To find the equation for the line of symmetry, we can use the formula x = -b/2a. For the given function, y = x^2 - 4x - 5, we can determine the values of a and b from the equation.
a = coefficient of x^2 = 1
b = coefficient of x = -4
Now, using the formula x = -b/2a, we can calculate the x-coordinate of the vertex, which is also the line of symmetry.
x = -(-4) / (2*1)
x = 4/2
x = 2
Therefore, the line of symmetry for the graph is x = 2.
