~~~~~~~~~~~~~~~~~~

In your formula for f(x), there are two opening parentheses and only one closing parenthesis.

Thus, the formula is WRONG.

The assignment, prepared so carelessly, can not be accepted for execution.

Be more attentive, accurate and responsible, while posting to this forum.

Also, from the post I see that that the missed parenthesis is not only one your mistake: there are others, too.

Thoroughly find and fix all your errors; then re-post to the forum.

Please do not post it to me in person.
