Summary. "Function Composition" is applying one function to the results of another. (g º f) (x) = g (f (x)), first apply f (), then apply g () We must also respect the domain of the first function. Some functions can be de-composed into two (or more) simpler functions. Mathopolis: Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10. Imaginary number. An imaginary number is a real number multiplied by the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1] [2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. By definition, zero is considered to be both real and imaginary.The Real Number Line is like a geometric line. A point is chosen on the line to be the "origin". Points to the right are positive, and points to the left are negative. A distance is chosen to be "1", then whole numbers are marked off: {1,2,3,...}, and also in the negative direction: {...,−3,−2,−1}In mathematical operations, “n” is a variable, and it is often found in equations for accounting, physics and arithmetic sequences.

All real numbers greater than or equal to 12 can be denoted in interval notation as: [12, ∞) Interval notation: union and intersection. Unions and intersections are used when dealing with two or more intervals. For example, the set of all real numbers excluding 1 can be denoted using a union of two sets: (-∞, 1) ∪ (1, ∞)You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: −2 > −5 since −2 is to the right of −5 on the number line.The symbols for Complex Numbers of the form a + b i where a, b ∈ R the symbol is C. There is no universal symbol for the purely imaginary numbers. Many would consider I or i R acceptable. I would. R = { a + 0 ∗ i } ⊊ C. (The real numbers are a proper subset of the complex numbers.) i R = { 0 + b ∗ i } ⊊ C.3. The standard way is to use the package amsfonts and then \mathbb {R} to produce the desired symbol.
