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.

How do I do this please help I'm in tears

irakobra [83]

F(x) is vertically stretched by a factor of 5/4 matches w/ f(x)-5/4
f(x) reflects the x axis matches w/ -f(x)
f(x) is translated 5/4 units up matches with f(x)+5/4
f(x) translated 5/4 to the left matches w/ f(x)-5/4

I didn't really know about this one but it seemed kind of easy, what was your first guesses and did you forget to put one more or was the question like that.

Hope this is right :) or if someone else has a different answer but in the meantime, good luck :)

WILL GIVE BRAINLIEST!!!!! PLS ANSWER ASAP!!!!!

Answer:

The coordinates of the image trapezoid are

A"(-4,5), B''(-1,5), C''(0,3), D''(-5,3)

The pre-image was first reflected in the line y=x, so the mapping will be

The resulting coordinates were then translated 4 units right;

For A''(-4,5), y+4=-4 and x=5

This means y=-8, x=5

Hence A(5,-8)

For B''(-1,5), y+4=-1, and x=5.

This means y=-5 and x=5

B(5,-5)

For C''(0,3), C(3,-4)

For D''(-5,3), D(3,-9)

Step-by-step explanation:

there u go
