1. What is the value of cubeByVolume(9)?
2. 9^3 = 729.
3. What is the value of cubeByVolume(cubeByVolume(2))? a. cubeByVolume(8) = 512.
4. Using the pow() function, write an alternate implementation of the cubeByVolume function.

double cubeByVolume(double sideLength) {
  return pow(sideLength, 3.0);
}

4. Define a function called squareArea that computes the area of a square of a given sideLength.

double squareArea(double sideLength) {
  return pow(sideLength, 2.0);
}

5. Consider this function:

int mystery( int x, int y) {
  double result = (x + y ) / ( y - x);
  return result;
  }

What is the result of mystery(2,3) and mystery(3,5). a. 5 and 4. 6. Implement a function that returns the minimum of three values.

// Prototype
int findTheSmallest(int, int, int);
// Implementation
int findTheSmallest(int x, int y, int z) {
  if (x < y && x < z) {
    return x;
  } else if (y < x && y < z) {
    return y;
  }
  return z;
}
// Function call
findTheSmallest(1,2,3);
// => 1
