If for a function `f(x),f^'(a)=0,f^(' ')(a)=0,f^(a)>0,` then at `x=a ,f(x)` is minimum (b) maximum not an extreme point (d) extreme point

If for a function f(x),f'(a)=0,f"(a)=0,f'''(a)gt0, then at x=a,f(x) is

If for a function f(x),f'(2)=0,f''(2)=0,f''(2)>0 then x=2 is -

If for a function f(x),f'(2)=0,f(2)=0,f'(2)>0, then x=2 is

If a function f(x) has f'(a)=0 and f''(a)=0, then x=a is a maximum for f(x)x=a is a minimum for f(x) it is difficult to say (a) and (b)f(x) is necessarily a constant function.

Let f(x) be a function such that,f(0)=f'(0)=0,f''(x)=sec^(4)x+4 then the function is

A function y=f(x) satisfying f'(x)=x^(-(3)/(2)),f'(4)=2 and f(0)=0 is

There exists a function f(x) satisfying 'f (0)=1,f(0)=-1,f(x) lt 0,AAx and
