Consider the function:



f(x) = StartLayout enlarged left-brace 1st Row 1st column seven-halves + 2x, 2nd column x less-than-or-equal-to negative 1 2nd row 1st column negative 5 + StartFraction 3 x Over 2 EndFraction, 2nd column Negative 1 less-than x less-than 3 Third row 1st column one-fourth x, 2nd column x greater-than-or-equal-to 3 EndLayout


A number line goes from negative 5 to 5.
What are these values?



f(−3) =



f(−1) =



f(3) =
