Please explain why the answer is what is is thoroughly. I am trying to study for my test. I will make sure to thumbs up! thank you very much for your time

9. A function named integrate that integrates a mathematical function f can be made as general as possible by passing f as an argument. Which one of the following function prototypes correctly declares a function that uses function pointer as an argument? Parameter a and b are the range for the integration. a) double integrate (double f, double a, double b); b) double integrate f (double x), double a double b c) double integrate (double f) double x), double a double b d) double integrate double *f (x) double a, double b e) None of above Answer 10. The following structures are designed to store information about objects in a Cartesian coordinate system struct point int x, y struct rectangle int upper left x, upper left y, lower right x, lower right y; A point structure stores the x and y coordinates of a point. A rectangle structure stores the coordinates of the upper left and lower right corners of a rectangle. Which of the following functions will correctly determine whether a point p lies with n rectangle r, return 1(true) or 0(false)? a. int is inside (struct point p struct rectangle r) return p. x r. upper left x && p.x r.1 ower right x & & p. y r. upper left y & & p. y r. lower right y b. int is inside (struct point p struct rectangle r return p.x r. lower right k & & p.x r. upper left x && p. y r. upper left y && p.y K- r. lower right y C. int is inside (struct point p struct rectangle r) return p x r. upper left x & & p.x r.1 ower right x && p.y r lower right y & & p y r upper left y a. int is inside (struct point p struct rectangle r return p.x r. lower right k & & p.x r. upper left x && p. y r. lower right y && p. y r. upper left y e. None of the above
