Question

Assertion (A): f left parenthesis x right parenthesis equals a x to the power of 2 end exponent plus b x plus c comma blank f o r blank a left parenthesis not equal to 0 right parenthesis comma b comma c element of R When a>0 and b to the power of 2 end exponent minus 4 a c less than 0 comma f left parenthesis x right parenthesis equals 0 has complex roots.
Reason(R): The graph of f left parenthesis x right parenthesis equals a x to the power of 2 end exponent plus b x plus c cuts x-axis.

  1. Both A and R are true and R is the correct explanation of A.    
  2. Both A and R are true and R is not the correct explanation of A    
  3. A is true but R is false    
  4. A is false but R is true    

The correct answer is: A is true but R is false
