f : R → R, f(x) = 2 + 3 x³ ; g : R → R , g(x) = -x + 1. (f ∘ g)(-1) = ?

Given that x is a real number and f is given by the rule f (x) = (2x - 12)^1/2 , which of the following sets is the largest domain of the definition of f ?

If ln 2=a, what will be the value of ln 0.5?

1. Consider the function . For every x₁, x₂  A if x₁ ≠ x₂ implies f(x₁) ≠ f(x₂) then the function f is called one-to-one (or injective).
2. Given a function  if the image is equal to the range, i.e. f (A)=B the function f is called surjective (onto).
3. If a function which is both one-to-one and onto is called a bijection.
4. Constant function and identity function are the concepts related to types of functions. A function assigning each element from its domain a single element in its range is called a constant function.
5. Given A ≠, a function defined on the set A and assigning every element of A to itself is called the identity function.

1. Two real lines intersecting perpendicularly at both their zeros constitute the Cartesian coordinate system.
2. The Cartesian coordinate system is a tool which enables us to view the graphs of functions.
3. In the Cartesian coordinate system, the horizontal real line is called the x-axis, or abscissa,
4. In the Cartesian coordinate system, the vertical real line is called the y-axis, or ordinate.
