Question 2

fomenos

Answer:

D. (-2,-5), (0, -7), (1, -4)

Step-by-step explanation:

From Function Theory we must remember that range of a function is the set of images related to elements of the domain. In this case, we must find the image of each of the three elements that forms the domain of $f(x, y) = (y+2, -x-4)$ , which are: $A(x,y) = (1, -4)$ , $B(x,y) = (3,-2)$ and $C(x,y) = (0,-1)$ .

Then we proceed to find all elements of range:

$A(x,y) = (1, -4)$

$f(1,-4) = (-4+2,-1-4)$

$f(1,-4) = (-2,-5)$

$B(x,y) = (3,-2)$

$f(3,-2) = (-2+2,-3-4)$

$f(3,-2) = (0,-7)$

$C(x,y) = (0,-1)$

$f(0,-1) = (-1+2,0-4)$

$f(0,-1) = (1,-4)$

Which corresponds to option D.

From the beginning of cross country season to the end , Trisha reduced her time by 17 % , Anchara reduced hers by 4/25 , and Jua

kati45 [8]

Trisha - 17 percent
Anchara - 4/25 = 0.16 = 16 percent
Juanita - 16 - 13.3 = 2.7 2.7/16 (since 16 is the total) = 0.16875 = 16.875 percent

So Trisha reduced her time by the greatest percent (17)

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?

satela [25.4K]

Step-by-step explanation:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{ - 5 + - \sqrt{ {5}^{2} - 4(5) } }{2} \\ x = \frac{ - 5 + - \sqrt{25 - 20} }{2} \\ x = \frac{ - 5 + - \sqrt{5} }{2}$

Therefore, the zeroes would be:

$x1 = \frac{ - 5 + \sqrt{5} }{2} \\ x2 = \frac{ - 5 - \sqrt{5} }{2}$
