To find the value of $$ f(4) $$ for the function $$ f(x) = 3 \cdot 5^{x} $$, follow these steps:

1. **Substitute $$ x = 4 $$ into the function:**
   $$
   f(4) = 3 \cdot 5^{4}
   $$

2. **Calculate $$ 5^4 $$:**
   $$
   5^4 = 5 \times 5 \times 5 \times 5 = 625
   $$

3. **Multiply by 3:**
   $$
   f(4) = 3 \times 625 = 1875
   $$

**Answer:**  
d.) 1875
$$ f(4) = 1875 $$
