b) Find the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation. If an answer does not exist, enter DNE.)

increasing: (?, ?) ***the answer is NOT (0, ∞)

decreasing: (-1, 0)

c) Apply the First Derivative Test to identify the relative extremum. (If an answer does not exist, enter DNE.)

Consider the following function main:
Int main()
{
int inStock[10][4];

}

a) Write the definition of the function setZero that initializes any one-dimentional array of type int to 0.
b) Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha.
c) Write the definition of the function doubleArray that initializes the elements of beta to two times the corresponding elements of alpha. Make sure that you prevent the function from modifying the elements of alpha.
d) Write the definition of the function copyGamma that sets the elements of the first row of inStock to gamma and the remaining rows of inStock to three times the previous row of inStock. Make sure that you prevent the function from modifying the elements of gamma.
e) Write the definitions of the function copyAlphaBeta that stores alpha into the first five rows of inStock and beta into the last five rows of inStock. Make sure that you prevent the function from modifying the elements of alpha and beta.
f) Write the definition of the function printArray that prints any one-dimensional array of type int. print 15 elements per line.
g) Write the definition of the function setInStock that prompts the user to input the elements for the first column of inStock.
