If a vertical line cuts a graph in more than one point, then it is a function? For any set X a function I ? X ® X or I(x) = x, " x e X, it is called an inverse function? When variables x & y are expressed in terms of another variable, then it is called polynomial function?

Cosine function is an even function? Let f & g be function defined on variable x then f g(x) = gf(x)? If f(x) = 3x + 2 also f(x) = 17, then x = 5? If f(x) = sin x + cos x then it is neither an even nor an odd function? Volume of a cube can be expressed as the area of its base? A function A ? X ®Y defined by A(µ) = a is called function? If a point (a,b) lies on the graph of the function which of the following point must lie on the graph of inverse of f? ?
