Heather has the equation y 2 3x 1 She wants to graph a function that represents exponential decay What should she change in her equationA change the 2 to a 12B class=

Respuesta :

We have that:

- Raising a whole number to an exponent will make the value increase.

- Raising a fraction to an exponent, however, will make the value decrease.

- The +1 at the end is insignificant.

Therefore, given the function:

[tex]y=2\cdot3^x+1[/tex]

To find a new function that represents the exponential decay we must change the number 3.

Answer:

B. Change the 3 to a 1/3
