The domain of this, assuming it's a function, is all real numbers such that x does not equal zero or negative ten.

In interval notation, this is (-∞, -10) U (-10, 0) U (0, ∞).

In set builder notation, this is {x | x ≠ -10, x ≠ 0}.

These inputs are excluded from the domain because they would otherwise allow division by zero. Try plugging in one of the restricted inputs. You'll see that it does not work! On a graph of this function, you will see vertical asymptotes.

OLEGan [10]

The following code will be used to determine the maximum amount invested

Explanation:

long maxValue(int n, int rounds_rows, int rounds_columns, int into rounds)

{

// Define the variable to store

// the maximum amount invested.

long max = 0;

// Define an array of size n,

// to store the n investments.

long *investments = (long*)malloc(sizeof(long)*n);

int i=0;

// Initially set all

// the investments to 0.

for(i=0;i<n;i++)

{

investments[i] = 0;

}

i=0;

// Run the loop to

// perform the rounds.

while(i<rounds_rows)

{

// Get the left value

// of the current round.

int left = rounds[i][0];

// Get the right value

// of the current round.

int right = rounds[i][1];

// Get the contribution

// for the current round.

int contribution = rounds[i][2];

// Since the user uses 1-based

// indexing, subtract 1 from left

// and right as the program uses

// 0-based indexing. That is, the

// investments in the array start

// from 0 and not 1.

right = right - 1;

int j=0;

// Run the loop to add the

// contribution to all the investments

// between left and right, both inclusive.

for(j=left; j<=right; j++)

{

investments[j] += contribution;

}

i++;

}

// Traverse the investments array

// to find the maximum element.

max = investments[0];

for(i=1; i<n;i++)

{

if(investments[i]>max)

{

max = investments[i];

}

// Return the

// maximum investment.

return max;

}
