Question

Objective - To draw a graph of a quadratic polynomial [p(x)=ax2=bx+c=0],by assuming a particular case and observe the shape of curve for the following case- Case-1: When,a>0 Case-2:When,a<0

Answer 1

Let ax2+bx+c=y⇒x2+abx+ac=ay⇒x2+22abx+(2ab)2=ay+(2ab)2⇒(x+2ab)2=ay+(2ab)2⇒X2=Y  

X=f(x)&Y=f(y).

So it s an equation of a parabola.

The graph will be that of a parabola.
