The Function Models The Change In Yearly Value For Annas Cell Phone Period What Is The Original Value Of A Cell Phone Does The Function Represent Exponential Gr class=

Answer :

Answer:

• The original value of a cell phone is 650

,

• The function represents exponential decay

Explanation:

Given the model

[tex]y=650(0.77)^x[/tex]

The original value of a cell phone is when x = 0

Substituting x = 0 in the given model, we have:

[tex]\begin{gathered} y=650(0.77)^0 \\ =650(1) \\ =650 \end{gathered}[/tex]

The function represents exponential decay, because 0.77 is between 0 and 1.
