1 QuantifiersConsider the domain of integer numbers, and let P(x) be the statement x < x³. For each of thefollowing formulas determine their truth values. You must justify your answers. Simply stating trueor false will give you no credit, even if your answer is correct.а) Р(2)b) Р(-1)c) VxP(x)d) 3xP(x)e) 3!xP(x)

2. Let P(x) be "x is a student in this class," Q(x) be “x knows how to write programs in Python," and R(x) be “x can get a good job," where the domain of x consists of all people. Write the following argument in argument form and use the rules of inference to show that the argument is valid. Tom is a student in this class. Tom knows how to write programs in Python. Everyone who knows how to write programs in Python can get a good job. Therefore, some student in this class can get a good job.
