Please write the for loop in Octave.

1.2.18: A function f is defined by the series 00 f(x) = (-1)+1 = k=1 Use the Alternating Series Theorem (p. 29) to figure out how many terms would be needed to compute f(1) with error less than or equal to 10-8. Using this number, write a quick for loop to evaluate f(1) and record the value with at least 8 decimal places
