Three good friends are in the same algebra class. Their scores on a recent test are three consecutive even integers whose sum is
klio [65]

Let the lowest score be x.

<u>The 3 consecutive even scores are:</u>

1st score = x

2nd score = x + 2

3rd score = x + 4

-

<u>Sum of their score is 270:</u>

x + (x + 2) + (x + 4) = 270

-

<u>Solve x:</u>

x + (x + 2) + (x + 4) = 270

x + x + 2 + x + 4 = 270

3x + 6 = 270

3x = 264

x = 88

-

<u>Find their scores:</u>

1st score = x = 88

2nd score = x + 2 = 88 + 2 = 90

3rd score = x + 4 = 88 + 4 = 92

-

Answer: The scores are 88, 90 and 92

The end behaviour for the polynomial function h(x)=−x3+x4−2x+1 h ( x ) = - x 3 + x 4 - 2 x + 1 is: x→−[infinity], y→−[infinity]
Goryan [66]

Answer:

\text{As  } x \to \infty, y  \to \infty,$and as  x \to -\infty, y  \to \infty

Step-by-step explanation:

Given the polynomial function: h(x)=-x^3+x^4-2x+1

To examine its end behavior, we create a table of values that we can then examine.

\left|\begin{array}{c|c}x&h(x)\\--&--\\-4&329\\-3&115\\-2&29\\-1&5\\0&1\\1&-1\\2&5\\3&49\\4&185\end{array}\right|

From the table, we see a repeating pattern of positive values of h(x) with h(1)=-1 being an axis of symmetry.

Therefore, as:

x \to \infty, h(x)  \to \infty\\x \to -\infty, h(x)  \to \infty
