SigmaHow move and resize the graphs of functions? How move the graphs of functions? Add a constant to the y-value will move it up or down Add a constant to the x-value will move it left or right Examples Function c > 0 c < 0 f(x) = x2 g(x) = x2 + c f(x)
Definition of Absolute Value Absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign. |x| = x for a positive x, |x| = −x for a negative x (in which case −x is positive) |0| = 0. For example, the absolute value of 5 is
Definitions Conjugate is where we change the sign in the middle of two terms The conjugate of “a + b” is “a – b” Conjugate is only used in expressions with two terms (binomials) Examples Expressions Conjugate a + 1 a – 1 b2 – 2 b2 + 2 4 + √3 4 – √3 When we
Definition of Pyramid Pyramid is one of polyhedron form that connecting polygonal as the base and a point that called apex/vertex. As consequences there are base (polygonal that is like triangle, square, etc.) and some triangle sides as lateral sides. Type of Pyramid Depends on the Base Number of triangle depends on what type polygonal
Definitions There are 3 types of fractions Fraction type Condition Examples Proper Fraction Numerator < Denominator Improper Fraction Numerator > Denominator Mix Fraction A whole number + proper fraction So, An Improper Fraction is a fraction that has a top number larger than (or equal to) the bottom number.
