Answer:

y = x^2 - 4x - 6.

Step-by-step explanation:

The roots are  2 + √10 and 2 - √10, so in factor form we have:

(x -  (2 + √10))(x - (2 - √10))

= ( x -  2 - √10)(x - 2 + √10)

= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x  + 2√10 - √100

=  x^2 -4x + 4 - 10

= x^2 - 4x - 6.

Which function is represented by the graph? f(x) = â’|x â’ 3| 4 f(x) = â’|x 3| 4 f(x) = â’|x â’ 4| 3 f(x) = â’|x 4| 3.
irinina [24]

Functions are used to represent graphs, and vice versa.

The function represented by the graph is f(x) =- |x + 4| + 3

The graph (see attachment) is an absolute value graph.

An absolute value graph is represented as:

f(x) =a |x - h| + k

Where

Vertex = (h,k)

The vertex is the minimum or the maximum point on the graph.

So, we have:

Vertex = (-4,3)

The function becomes

f(x) =a |x + 4| + 3

The function also passes through the point (-1,0).

So, we have:

0 =a |-1 + 4| + 3

0 =a |3| + 3

Remove the absolute bracket

0 =3a + 3

Subtract 3 from both sides

3a =- 3

Divide both sides by 3

a =- 1

Substitute -1 for (a) in f(x) =a |x + 4| + 3

f(x) =- |x + 4| + 3

Hence, the function represented by the graph is f(x) =- |x + 4| + 3

What is the measure of the third angle of a triangle if
dolphi86 [110]

Answer:

105°

Step-by-step explanation:

total angle of triangle equals 180°

so,

25° + 50° + ? = 180°

? = 180° - (25° + 50°)

? = 180° - 75°

? = 105°

So third angle of a triangle is 105°
