Which equation below will produce a decay curve?

y = 3^x - 4

y = 2 (4) ^x

y = 1/2 (3) ^x

y = 6 (1/3) ^x

Correct option: fourth one - > y = 6 (1/3) ^x

Step-by-step explanation:

A decay curve is produced by an exponencial function with a rate lesser than 1 and greater than 0. This way, we have an exponencial function where the values of y decrease when the values of x increase.

The first equation is a linear equation.

The second and third equations are exponencial equations, but with a rate bigger than 1

The fourth equation is an exponencial equation with a rate lesser than 1 and greater than 0, so this equation will produce a decay curve.
