Answer:
To find the value of y for a specific value of t, you can substitute the given value of t into the function:
\(y(t) = 1727.93 \cdot (1 + 9.21 - 0.65)^t\)
If you have a specific year in mind (t), you can calculate y by plugging in that value. For example, if you want to find the number of smartphones shipped in 2015 (which is 6 years after 2009), you would substitute t = 6 into the equation:
\(y(6) = 1727.93 \cdot (1 + 9.21 - 0.65)^6\)
\(y(6) = 1727.93 \cdot (9.56)^6\)
\(y(6) ≈ 1727.93 \cdot 48874.1\)
\(y(6) ≈ 84,462,853.33\)
So, according to the function, approximately 84.46 million smartphones were shipped in 2015.
