Two years ago, Marc bought a new cell phone. His purchase price was $750. The value of the phone for the next 2 years was $637.50 and $541.88, respectively. Find the exponential function that represents the value of Marc’s phone t years after it was purchased.(1 point) Responses f(t)=750⋅0.85t f left parenthesis t right parenthesis equals 750 times 0.85 superscript t baseline f(t)=750⋅0.85t f left parenthesis t right parenthesis equals 750 times 0.85 t f(t)=637.50⋅0.85t f left parenthesis t right parenthesis equals 637.50 times 0.85 superscript t baseline f(t)=750⋅1.15t
The correct exponential function that represents the value of Marc's phone t years after it was purchased is:
f(t) = 750 * 0.85^t
