EFFECT OF COEFFICIENT OF X^0 ON PARABOLA VERTEX
ConcepTest

Consider the general form of a quadratic function,  

    or     

If the coefficient c is increased in value, how will this increase affect the position of the vertex of the parabola?  

For the sake of simplicity, you may assume that both a and b are fixed values and that a=1 and b=4.  

The new vertex will be:

CIRCLE ONE:

A.	 LOWER THAN THE ORIGINAL VERTEX

B.  SAME POSITION AS THE ORIGINAL VERTEX

C.  HIGHER THAN THE ORIGINAL VERTEX
