How do you find the axis of symmetry, graph and find the maximum or minimum value of the function #y = (x - 1)^2 + 2#?
axis of symmetry
This is a quadratic equation that has been changed such that it is in vertex form. You virtually read the values you are asked to find almost directly from this.
Consider the -1 from
Multiply this by negative 1 giving
So the axis of symmetry is the line parallel to the y-axis defined by
We already have the value of x all we need now is the value for y.
As it happens this is the value of the constant in the equation
