why is the parameter a in the quadratic function not allowed to equal 0? what type of function would result if a = 0?
why do yo uthink parameter c is called a constant?
one ordered pair of coordinates defines a 0-dimensional space, or point, for example: (2,7). Two points define a 1-dimensional space, or straight line, for example: (1, 3) and (5, 2).
How many points do you think are required to define a 2-dimensional space, such as the graph of a quadratic function?
