If the graph of a differentiable function y = f (x) meets the lines y = – 1 and y = 1, then the graph

Let f be a real valued function defined on (0, 1) ∪ (2, 4) such that f ‘ (x) = 0 for every x, then

In case of strict decreasing functions, slope of tangent and hence derivative is

The function f (x) = 2 – 3 x is

The function f (x) = x² – 2 x is increasing in the interval

The function f (x) = x², for all real x, is

The function f (x) = m x + c where m, c are constants, is a strict decreasing function for all x ∈ R , if

Let f (x) = x³−6x²+9x+8 then f (x) is decreasing in
