I need help with these two questions!!

Question

The function y = (1/2)(3)^x is an example of
 

a quadratic equation

a higher order polynomial

exponential growth

exponential decay

 

 

 

The function y = (4)(1/2)^x is an example of
 

a quadratic equation

exponential growth

exponential decay

a higher order polynomial

Answer 1

The function y = (1/2)(3)^x is exponential growth

 

The function y = (4)(1/2)^x is exponential decay; the function is equivalent to y = 4•2^-x
