please solve all these Q :(

Q1) Put "T" for true statements and "F" for false ones. The expression lx?l - (2x - y). Is written in C++ as follows: abs(pow(X, 2)) - sqrt(pow(2, x) - y) a) Function heading and the body of the function are called the definition of the function. b) Parameters allow you to use different values each time the function is called c) You need to include function prototypes in a program that contains User defined functions? d) To use a predefined function in a program, you need to know only the name of the function and how to use it. e) A value-returning function returns only one value. f) When a return statement executes in a user-defined function, the function immediately exits. g) A return statement returns only one value. h) A function prototype is the function heading without the body of the function; the function prototype ends with the semicolon. i) A value-returning function returns only integer values Q2-Determine the value of each of the following expressions: a. ceil(36.1) d. pow(3.2, 2) g. pow(2.5, 3) j. fabs(11.8) b. pow(3.0, 4.0)/abs(-9) e. abs(-10) h. sqrt(38.2 c. fabs(-5.8) f. sqrt(36.0) i.floor(25.95) Q3-Consider the following statements: double num1, num2, num3; int int1, int2, int3; int value; num1 = 5.0; num2 = 6.0; num3 = 3.0; int1 = 4; int2 = 7; int3 = 8; and the function prototype: double cube(double a, double b, double c); Which of the following statements are valid? If they are invalid, explain why. a. value = cube (num1, 15.0, num3); b. cout
