Ok, a function means that the domain (x) does not repeat... so if you look at all of the first numbers in the ordered pairs or x and none of them are repeating in the set that is your answer. For this the answer would be 1 and not 2 because x has a exponent making it 2 x and not 3 because there is 2 10s. Let me know if this helps and you have any other questions.

For the function y=-2x^2+4x+1, what are the coordinates of the vertex? Is it a maximum or minimum point? Hint: use the vertex/ax

masya89 [10]

Step-by-step explanation:

y = -2x² + 4x + 1

Complete the square.

y = -2 (x² − 2x) + 1

y = -2 (x² − 2x + 1) + 1 − (-2)(1)

y = -2 (x − 1)² + 3

The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.

Use the law of cosines to solve for the measure of the largest angle in triangle abc.

MariettaO [177]

The law used for determining the measure of unknown sides and angles of a triangle. The measure of the largest angle in triangle abc is 98.25 degrees

<h3>Law of cosines</h3>

The law used for determining the measure of unknown sides and angles of a triangle. It is expressed as:

c² = a² + b² - 2abcosC

Given the following

c = 16

a = 12

b = 9

Substitute

16² = 12² + 9² - 2(9)(12)cosC

256 = 144 + 81 - 216cosC

31 = -216cosC

cosC = -31/216

C = 98.25 degrees

Hence the measure of the largest angle in triangle abc is 98.25 degrees
