Question

if a >0 and b²-4ac=0 then the graph of y=ax²+bx+c where will be the line placed
​

Answer 1

Answer:

is concave upwards

Step-by-step explanation:

Given quadratic equation : y=ax2+bx+c

If a>0, graph of the curve will be concave upwards.

and for b2−4ac<0, graph of the curve will not touch the x-axis at any points.

Hence, A is the correct option.
