- DEFINITION
- Equality between two
expresions that
contain one or more
variables.
- TYPES
- Linear equations
- ax+b=0
- Cuadratic equations
- ax2+bx+c=0
- Third grade ecuations
- ax3+bx2+cx+d=0
- Fourth grade equations
- ax4+bx3+cx2+dx+e=0
- n equations
- a1xn+a2xn-1.....+a0=0
- Racional polimians equations
- p(x)/Q(x)
- ORIGEN
- XVI: Egipcians sarted to
used equations to
resolve cotidian
problems.
- FUNCTIONS
- ORIGEN
- XVIII, Actually
knowed like"calculo"
- DEFINITION
- Relationship between
two or more cuantities
- TYPES
- Constant function
- f(x)=b (b is
constant
- linear function
- f(x)=mx+b
- Polinomial functions
- f(x)=anxn+an-1xn-1........+a0
- Cuadratic function
- f(x)=ax2++bx+c
- Racional function
- q(x)=f(x)/g(x)
- Independent variable.
- Its a letter that
repesent a series of
numbers that are
choosen with no
"criteria"
- h(x)=x2+7x+12
Independent=x
- Dependent variable
- Its a different letter in
the function or
notation whose value
is a consequence of
operating with the
previous chossen value
- h(x)=x2+7x+12
dependent=h(x)
- RANGE
- It is the set of all the values that result
as consequence of operating in the
function (y-values=y-axis)
- LOGARITHM
- a quantity representing the power to
which a fixed number (the base)
must be raised to produce a given
number.
- LOG in base b 5x
- exponent
- a quantity
representing the
power to which a
given number or
expression is to be
raised
- 2 raised 3 = 2 × 2 × 2
- DOMAIN
- set of all possible x-values which
will make the function "work",
and will output real y-values.
