1 My Function Family Album By:Algebra IIMay 20, 20097th pd.
2 Linear Functions Parent Function Parent Function of a liner function (Jesse).Jesse is the function to all linear functions . She's the base to their life.She has a domain and range of all real numbers.One of the many children of Jesse is f(x) = -x-2.Its domain and range is all real numbers to.Linear Function
3 Linear Functions (contd.) Another liner function of Jesse is her inequality children.Its domain and range are all real numbersInequality of a Linear Function
4 Absolute Value Functions Parent FunctionParent Function of an Absolute Value Function (Martha).She makes the shape of a V and has brackets around her to contain her absoluteness.Her domain is all real numbers and her range is all real numbers except non-positive numbers.
5 Absolute Value Functions (contd.) An example of a absolute function is f(x)=|-2x|-2Its domain and range is all real numbers.An inequality of an absolute value is the function of x is less than or equal to |x+4|-3It has a domain and range of a real numbers to.Inequality of aAbsolute Value Function
6 Quadratic Functions Parent Function The Parent Function of a Quadratic Function (Mr. Quadratic)Mr. Quadratic is a function who has a ² on him .He has many different ways of writing him and they are his power up levels:y=ax²y=ax² +cand y=ax² +bx+cHe also has a domain of all real numbers and a range of all real numbers except non-positive numbersParent Function
7 Quadratic Functions (contd.) Here’s an example of Mr. Quadratic on a power up levelIt has a domain of all real numbers and a range of all positive numbers.Mr. Quadratic's sidekicks are the inequalities of him here’s an example of one y is greater than or equal to -4x²-2It has a domain of all real numbers and a range of all non-positive numbersInequality of aQuadratic Function
8 Polynomial Function Polynomial Function Unfortunately the polynomial function doesn't have a parent function because it’s a such a dysfunctional family.But fortunately it has it own degree which is quartic.Its domain and range is all real numbers.Its inequality is x-5x²-3Inequality of aPolynomial Function
9 Square Root FunctionParent Function of Square Root Function (Mr. and Mrs. Square)They make semi straight lines and have the square root symbol within them (√) .There domain is x is greater than or equal to 0There range is y is greater than or equal to 0.Parent Function of aSquare Root Function
10 Square Root Functions (contd.) There Children are kind of tricky they like to add stuff for example they added a 2 on the outside and a plus one to the inside.There domain is x is greater than or equal to -1There range is y is greater than or equal to 0The inequality for the Square’s is √X-4+3There domain is all real numbers and there range is y is greater than or equal to 2.Inequality of aSquare Root Function
11 Cube Root Functions The Cube Root Parent Function (Mrs. Smith). Mrs. Smith is a cube who has a ³ on her.Her domain and range is all real numbers.Parent Function of aCube Root
12 Cube Root Functions Cube Root Function Her children are a simple replica of her with slight changes, for example ³√x-5She has a domain and rage of all real numbers just like her mom.Her grandchildren or inequalities just like this one ³√x-1)+1Its domain and range is the same as its mother all real numbersInequality of aCube Root Function
13 Rational Functions Parent Function of a Rational Function (Molly). Molly is the function you want when you want a rational answer.You can write her in three different ways:Y=a/xY=a/x-h+4Y=ax+b/cx+dHer domain and range all real numbers except 0.Parent Function of aRational Function
14 Rational Functions (contd.) An example of Molly’s rational function is f(x)= -4/x.Its domain and range is all real numbers except 0.An inequality of this function is function of x is less than 4 over x plus three.It has a domain and range of all real numbers except 0.Inequality of aRational Function
