standard_description: Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosines, and tangent for π–x, π+x, and 2π–x in terms of their values for x, where x is any real number.
problem_activity: Graph the quadratic function below by creating a table of values. Annotate the graph with features of the function.
$${j(x)=2x^2-6x+4}$$
