Exponential Functions

 $y\ =\ ab^{x\ }$  is a nonlinear function called 

• linear 

• quadratic 

• exponential 

• reflection 

 $For\ \ y\ =\ a\left(b\right)^{x\ }$  'a' represents the 

• origin 

• x - intercept 

• y - intercept 

• factor being multiplied by 

 $For\ y\ =\ a\left(b\right)^{x\ }$ 'b' represents the

• factor being multiplied by
  

• y - axis
  

• y - intercept
  

• none of these
