General Math Definitions #1 Flashcards
Is an algebraic expression that contains exactly one
term.
Monomial
Is the sum of one or more monomials.
Polynomial
Polynomial with one term
monomial
has the same output value no matter what your input value is. It has a form of f(x) = b, where b is a constant (a single value that does not change)
Constant Function
f(x) = b
Constant Function
Is a function that returns the same value which was used as its argument.
F(x)=x; for all values of x
Identity Function
F(2)=2 (x=2)
Identity Function
Y=7
Constant Function
Is defined by y = a0 + a1 + a2 … + anx
polynomial function
A polynomial function in the first degree.
It is in the form y=mx+b
Linear Function
y = 2x + 5
Linear Function
A polynomial function in the second degree
y = ax2 + bx + c
Quadratic Function
y = 3x^2 + 2x + 5
Quadratic Function
A polynomial of degree three and can be denoted by
f x = ax^3 + bx^2 + cx + d
Cubic Function
f x = ax^3 + bx^2 + cx + d
Cubic Function
f x = 5x^3 + 2x^2 + 3x + 6
Cubic Function
A polynomial function in the form y = ax^b
Power Function
y = ax^b
Power Function
f x = 8x^5
Power Function
A function that can be represented by p(x)
q(x) in which numerator,p(x) and the denominator, q(x) are polynomial functions of x, where q(x)≠0
Rational Function
f x =x2 − 3x + 2/ x2 − 4 «fraction»
Rational Function
They are functions of the form:
y = abx
where x = is an exponent
a and b = constants
Exponential Function
y = 2^x
Exponential Function
Are inverses of exponential functions, and any exponential function can be
expressed in logarithmic functions. It is written in the form:
y = logbx ; x > 0
Where b>0 and b≠1
Logarithmic Function
