Question 636516: A)Apply the quadratic formula to find the roots (x-intercepts) of the given function.
B)Graph the function – You will also need to find the vertex of each parabola, and most likely additional points to complete the graph. Label the roots (if plot-able) and the vertex with their ordered pairs
1. f(x)= x^2+ 4
2. g(x)= x^2+ x+ 12

Hi,

Note: the vertex form of a Parabola opening up(a>0) or down(a<0),  

where(h,k) is the vertex  and  x = h  is the Line of Symmetry

1. f(x)= x^2+ 4  | parabola opeing UPward, V(0,4), doesNOT cross x-axis

2. , parabola opeing UPward, V(-1/2,11.75), doesNOT cross x-axis
