Evaluate the piecewise-defined function at the indicated values, and sketch its graph: f of x = 5 when x is less than 2, and f of x = 2x minus 2 when x is greater than or equal to 2. Evaluate f of negative 3, f of 0, f of 2, f of 3, and f of 5

Evaluate the piecewise-defined function at the indicated values, and sketch its graph: f of x = 3x when x is less than or equal to 0, f of x = x + 1 when 0 is less than x which is less than or equal to 2, and f of x equals left paren x minus 2 right paren squared, when x is greater than 2. Evaluate f of negative 5, f of 0, f of 1, f of 2, f of 3, f of 4, and f of 5
