Answer :

The function's value, f(t), is 141. This is determined by simplifying the given expression F(8) step by step: adding positive and negative terms in the expression.

In order to find the value of the function f(t), we need to evaluate the given expression F(8):

F(8) = 84 – 593 + 682 – 18 83 — 382

Simplifying step by step:

1. 84 – 593 = -509

2. 682 – 18 = 664

3. 83 — 382 (This seems to be a typo as there's no clear operation between 83 and 382. Assuming it's subtraction) = -299

Now, the expression becomes:

F(8) = -509 + 664 - 299

Calculating the sum:

F(8) = -144

However, this seems to be a mistake, as the initial given expression seems to be a result of misinterpreted or corrupted text. Assuming the expression was meant to be:

F(8) = 84 – 593 + 682 – 18 - 83 - 382

Now, proceeding with the correct expression:

1. 84 – 593 = -509

2. 682 – 18 = 664

3. -83 - 382 = -465

Now the corrected expression becomes:

F(8) = -509 + 664 - 465

Calculating the sum:

F(8) = -310

So, the correct value of the function F(8) is -310, and therefore, the value of f(t) is -310.
