Question

If f(x)=ax²+bc+c has no real zeros and a+b+c<0, then​

Answer 1

Answer:

The graph of the function satisfying the given conditions is shown in the above picture.

We can observe that the graph doesn't touch the X-axis i.e. it doesn't have any real roots and the value of f(1)=a+b+c<0.

Now substitue x=0.

Then we can observe that f(0)=c<0
