Second option: down on the left, down on the right.

Clearly when x is bigger than one the term -x^38 will dominate the result.

When absolute value of x grows, x^38 becomes a larger positive number and - x^38 a larger negative number. Then both ends of the function tend to negative infinity.

Answer:

Down on the left, down on the right

Which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − StartRoot x EndRoot 8x3+ StartFraction 5 Over x E
kati45 [8]

Answer:

6x^2 - 6x + 5

Step-by-step explanation:

Given

List of Options

Required

Which of the options has a degree of 2

The general format of a polynomial is

ax^n + bx^{n-1} + ..... + cx^{n-n}

<em>Where n represents the degree </em>

In this case;

n = 2

Substitute 2 for n in expression above;

ax^n + bx^{n-1} + ..... + cx^{n-n}

ax^2 + bx^{2-1} + ..... + cx^{2-2}

ax^2 + bx^{1} + ..... + cx^{0}

ax^2 + bx + c *1

ax^2 + bx + c

Comparing this format to the list of given options; the option with the same format is: 6x^2 - 6x + 5

Where a = 6; b = -6 and c = 5

<em>Hence, the polynomial with a degree of 2 is </em>6x^2 - 6x + 5

The three angles of a triangular flag are x, twice the complement of x, and one-half the supplement of x
Angelina_Jolie [31]
Let x be the first angle
y be the second angle
z be the third angle.

for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90

then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60
