True. The expression \( y = f(x) = -3x + 3.5 \) represents a linear function. A function is defined as a relation that assigns exactly one output (in this case, \( y \)) for each input (in this case, \( x \)). Since this equation produces a unique \( y \) for every value of \( x \), it is a function for all real values of \( x \).
true or false: y=f(x)=-3x+3.5 is a function for all values of
