What is the standard form of a quadratic equation?
y = ax^2 + bx + c
y = mx + b
y = a(x - h)^2 + k
y = x^3 + bx + c
In the quadratic function y = x^2 - 4x + 3, what is the vertex?
(2, -1)
(1, -2)
(4, 1)
(3, 0)
Using Desmos, how can you find the x-intercepts of the quadratic y = x^2 - 5x + 6?
Plot the graph and look for points where the graph crosses the x-axis.
Use the vertex to find the x-intercepts.
Substitute y = 0 and solve the resulting equation using a graph.
Set the leading coefficient to zero and solve for x.
