Without using technology, describe the end behavior of f(x) = -3x4 + 7x2 - 12x + 13.

down on the left down on the right

down on the left, up on the right

up on the left, down on the right

up on the left, up on the right

Option 1 - Down on the left down on the right

Step-by-step explanation:

Given : Function

To find : Without using technology, describe the end behavior of f(x) ?

Solution :

Without technology we apply characteristics of Power and Polynomial Functions

As in function

The the end behavior of power functions of the form   where  n  is a non-negative integer depending on the power and the constant.

The leading term,

Negative constant and even power.

So, At

At

i.e. the curve approaches down on the left and down on the right.

Therefore, option 1 is correct.
