We are given with the polynomial above and is asked to evaluate the end behavior of the function.  The end behavior of a polynomial function is the behavior of the graph<span> of f ( x ) as x approaches positive infinity or negative infinity. As x approaches negative infinity, the function goes to negative infinity while when x</span> approaches positive infinity, the function goes to <span>positive</span> infinity

Answer:

As x ----> ∞, y----> ∞

As x ----> -∞, y----> ∞

Step-by-step explanation:

y = 7x^12 – 3x^8 – 9x^4

To find the end behaviour, we look at the leading coefficient and the largest exponent

In the given equation, the largest exponent is 12 that is an even number

the leading term is 7x^12, so leading coefficient is +7

When the largest exponent is even and leading coefficient is positive then the graph of y goes up(to infinity) on the left as well as on the right side of x

As x ----> ∞, y----> ∞

As x ----> -∞, y----> ∞

Help me please ill give brainliest give the CORRECT answer please
Neporo4naja [7]

Answer:

  174 ft²

Step-by-step explanation:

Assuming you're interested in the area of the figure, you can compute it as the sum of the areas of the triangle and rectangle.

The unknown side of the triangle can be figured from the overall dimension of the rectangle and the two lengths that are not part of the triangle base:

  6 ft + triangle base + 6 ft = 18 ft

  triangle base = 18 ft - 12 ft = 6 ft

Then the area of the triangle is ...

  A = 1/2bh = 1/2(6 ft)(4 ft) = 12 ft²

__

Of course, the area of the rectangle is the product of its length and width:

  A = LW = (18 ft)(9 ft) = 162 ft²

__

The total area of the figure is the sum of these:

  area = triangle area + rectangle area

  area = 12 ft² +162 ft²

  area = 174 ft²
