Sequences - Graphs and Functions

Which function family is shown in the graph?

• Absolute Value

• Linear

• Exponential

• Quadratic

Which type of sequence is shown in the graph?

• Arithmetic

• Geometric

• Neither

Find the explicit formula for the sequence shown in the graph.

•  $a_n=2\left(3\right)^{\left(n-1\right)}$  
  

•  $a_n=3+2\left(n-1\right)$  
  

•  $a_n=2+3\left(n-1\right)$  

•  $a_n=2+5\left(n-1\right)$  

Simplify the explicit formula for the sequence shown in the graph so that it is in function form.

•  $f\left(n\right)=3+2n$  
  

•  $f\left(n\right)=-1+3n$  
  

•  $f\left(n\right)=2+3n$  
  

•  $f\left(n\right)=5+3n$
