Question 593353: y = x^2 -4x +5, provide y values, how many x-intercepts are on the graph and determine the vertexof this parabola in (x,y) form and explain how it was found.
The -coordinate of the vertex of is given by . The -coordinate is found by evaluating which is to say calculate the value of .
To find the number of -intercepts evaluate the Discriminant. Calculate . If , then there are 2 -intercepts. If , then there is 1 -intercept. If , then there are 0 -intercepts.
