Let f(x)={:{[x^(2) if xlex_(0)], [ax +b if xgtx_(0)]:} if 'f' is differentiable at x_(0) then

If f(x)={ax^(2)+b,x 1;b!=0, then f(x) is continuous and differentiable at x=1 if

Let f(x) =ax^(2) -b|x| , where a and b are constants. Then at x = 0, f (x) is

Let f(x)=x^(2)+ax+b , where a, b in R . If f(x)=0 has all its roots imaginary, then the roots of f(x)+f'(x)+f''(x)=0 are

Let f(x)=x^(2)+ax+b, where a,b in R. If f(x)=0 has all its roots imaginary then the roots of f(x)+f'(x)+f(x)=0 are

Let f(x)=x^(2)+ax+b , where a, b in R . If f(x)=0 has all its roots imaginary, then the roots of f(x)+f'(x)+f''(x)=0 are

If f: Z to Z be given by f(x)=x^(2)+ax+b , Then,

If f: Z to Z be given by f(x)=x^(2)+ax+b , Then,

If f(x) {:(=x^(2)+ax+b", if "0 le x lt 2 ),(= 3x+2", if " 2 le x le 4 ),(=2ax + 5b ", if " 4 lt x le 8 ) :} is continuous on [ 0,8] then a-b = ……
