Without graphing determine whether the function represents exponential growth or exponential decay. y=4(5/6)^x y=12(17/10)^x y=129(1.63)^x

Since 5/6 is less than 1, hence the exponential equation is an exponential decay

Since 1.7 is greater than 1, hence the exponential equation is an

exponential growth

Since 1.63 is greater than 1, hence the exponential equation is an exponential growth

The standard form of an exponential equation is

The value of "b" in the expression determines whether the exponential equation given is s decay or an exponential growth

For the exponential equation

Compared with the standard expression, we will see that b = 5/6

Since 5/6 is less than 1, hence the exponential equation is an exponential decay

Similarly for the exponential equation

Compared with the standard expression, we will see that b = 1.7

Since 1.7 is greater than 1, hence the exponential equation is an

exponential growth

Also,  for the exponential equation

Compared with the standard expression, we will see that b = 1.63

Since 1.63 is greater than 1, hence the exponential equation is an exponential growth
