Question

If all the roots of f(x) =0 are real, then the roots of f'(x), f''(x), f'''(x) are​

Answer 1

Answer:

Step-by-step explanation:

Given : f (x) =0

condition for real  : D>0(1) ;D=0(2)

f'(x) and by using the condition (2) ='(0=0)

f'(x) and by using the condition (1) = '(0>0)

f"(x) and by using the condition (2) = "( 0=0)

f"(x) and by using the condition (1) = "(0>0)

f"'(x) and by using the condition (2) = "'(0=0)

f"' (x) and by using the condition (1) = "'(0>0)
