To find the value of the car after 5 years using the function \( f(x) = 35,000(0.85)^x \), we will substitute \( x = 5 \) into the equation.
Calculating \( f(5) \):
\[ f(5) = 35,000(0.85)^5 \]
First, calculate \( (0.85)^5 \):
\[ (0.85)^5 \approx 0.4437 \quad (\text{using a calculator}) \]
Now substitute this value back into the equation:
\[ f(5) = 35,000 \times 0.4437 \approx 15,034.50 \]
Rounded to the nearest cent, the value of the car after 5 years will equal $15,034.50.
