Here is a Python function to activate the remote

import numpy as np

def relu(x):
        """
        Relu activation function.

        :param x: Input.
        :return: Output.
        """
        return x * (x > 0)

# Enter the array
x = np.array([-1, 0, 1])

# Calling the function
print((relu(x)))

#Example Output
# [0 0 1]

#Remember to inspect code for bugs.
