Answer:

(-1)² = 1

(-1)³ = - 1

we can conclude that

• power of even no. results +ve result
• power of odd no. results -ev result.

according to the question

there will be 100 function

out of 100

• 50, (-1)^ even will be +ev .
• 50, (-1)^ odd will be -ev .

so, the result will be 0

50 × ( 1) + 50 ×( -1)

50 -50
