Transcribed Image Text:The function \( f(x) \) is defined piecewise as follows:
- For \( 3 \leq x \leq 5 \), \( f(x) = 0.05x + 0.3 \).
- Otherwise, \( f(x) = 0 \).
This piecewise function means that within the interval from 3 to 5 (inclusive), the function follows a linear equation \( 0.05x + 0.3 \). Outside this interval, the function is zero.
Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
