1. Independent

   • x-axis/input
     • Dependent
       • y-axis/output
   • m=-2(t+3)^2
     • Indepent variable =2
     • Dependent variable=m

2. Relation

   • Only set of ordered pairs

3. Function

   • A relation where each input has only one output

4. Equation of h as function of t

   • h=5t+1

5. Function notation

   • f(x)=x^2
   • 2x+5
     • f(x)=2x+5
   • f(1)
     • f(x)=2(1)+5=7

6. Inequalities
