Is there an image ? because it not showing to me
1) A
time (week) 1 2 4 8 10
time (days) 7 14 28 56 70
B
X= days ( depended )
Y= weeks ( independed)
you should find the constant: Y= x/1 ( well in fact i dont remember)
you'll ask. why? well, days depends of the weeks that are
2)
oxygen atoms 2 5 17 120
hdrogen atoms 4 10 34 480
y=x/4
a little problem: i didnt remember the order of the X and Y, but i think is ok
|x - (-22)| > 88 . . . . . the difference from -22 is more than 88
-88 > x +22 . . . or . . . x +22 > 88 . . . . "unfold" the absolute value
-110 > x . . . or . . . x > 66 . . . . . . subtract 22
Answer:
is there supposed to be a picture? or something you need help with?
Step-by-step explanation:
F(x)=-(x+5)(x+2)
f(x)=-(x^2+5x+2x+10)
f(x)=-(x^2+7x+10)
f(x)=-x^2-7x-10
df/dx=-2x-7 and d2f/dx2=-2
Since d2f/dx2, acceleration, is a constant negative, when df/dx, velocity, equals zero, f(x) is at an absolute maximum.
df/dx=0 when -2x-7=0, -2x=7, x=-3.5
f(-3.5)=22.25
The end behavior, as x approaches ±oo is simply the behavior of y as the leading term when x approaches ±oo.
-x^2 as x approaches ±oo approaches -oo
So the range of this function is y=(-oo, 22.5]
