What is the end behavior of the graph of the polynomial function f(x) = 2x3 _ 26x _ 24?

slamgirl [31]

Polynomial end behavior determines the value of the polynomial function as the value of x variable decreases in both the positive and negative direction.

For an expression with odd degree and a positive coefficient, its behavior is the same as x^3.

Thus for 2x^3 – 26x – 24;

<span>x -> - increasing y -> - increasing</span>

<span>And as x -> + increasing y -> + increasing</span>

32. At 8 AM, the temperature was 3°F below zero. By 1pm, the temperature rose

snow_lady [41]

Answer: - 1°F

Step-by-step explanation:

Given that:

At 8a.m:

Temperature = 3°F below 0

By 1p.m ; Temperature rose by 14F ;

By 10pm ; temperature dropped by 12F

Temperature at 10 pm:

3°F below 0 = - 3°F

Temperature at 1pm: temperature increased by 14°F

-3°F + 14°F = 11°F

Temperature at 10pm: temperature dropped by 12°F

11°F - 12 = - 1°F

If you know that 84 is 70% of the whole, explain how you can use proportional reasoning to determine the whole. Use the drop-dow

Akimi4 [234]

Answer: The value of whole is 120.

Step-by-step explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

$84=\dfrac{70}{100}\times x\\\\84=0.7\times x\\\\\dfrac{84}{0.7}=x\\\\120=x$

So, we have use the proportion i.e. $\dfrac{84}{70\%}=\dfrac{84}{0.7}$ to determine the value of whole.

Hence, the value of whole is 120.
