Which function does this graph correspond to?
tiny-mole [99]
ANSWER

The function that the given graph corresponds to is
f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)



EXPLANATION

The given graph in the attachment has x-intercepts at

x =  - 2 ,x=-1,x=1  \:  \: and   \: \: x=2


These are the solutions of the polynomial function represented by the given graph.




We can write all these solutions as factors to obtain,

x  + 2  ,x + 1 ,x - 1   \:  \:and \:  \: x - 2


The product of all these factors gives us the function whose graph was drawn.


This implies that,

f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)


Therefore the correct answer is option C.

Type the correct answer in each box.<br><br> The value of x is °, and the value of y is <br> °.
Solnce55 [7]

Answer:

<h2>x = 60°, y = 50°</h2>

Step-by-step explanation:

We know: the angles measures in a triangle add up to 180°.

<em>(look at the picture)</em>

z + 50 + 60 = 180

z + 110 = 180    <em>subtract 110 from both sides</em>

z = 70°

x + 50 + 70 = 180

x + 120 = 180         <em>subtract 120 from both sides</em>

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180         <em>subtract 130 from both sides</em>

y = 50°
