To analyze the function \( f(t) = 4t + 95 \), let's look at both the domain and range.
1. **Domain**: The function is a linear function, which means it is defined for all real numbers. There are no restrictions on \( t \) (e.g., no denominators that could be zero or square roots of negative numbers).
2. **Range**: Since the function is linear and has a non-zero slope (4), as \( t \) takes on all real numbers, \( f(t) \) will also take on all real values. As \( t \) approaches positive or negative infinity, \( f(t) \) will also approach positive or negative infinity.
Based on this analysis, we can conclude that:
- The domain of the function is made up of all real numbers.
- The range of the function is also made up of all real numbers.
Therefore, the correct statement is:
**The domain and range of the function are both made up of all real numbers.**
