Answer:
-212.5
Step-by-step explanation:
-212.5 x 0.4 = -85
Step-by-step explanation:
please write clearly and row wise understand problem
Answer:
neither
Step-by-step explanation:
The second and 3rd one can be modeled by by y = 100/x but the first one and the fourth one do not follow that, so the answer is neither. The first and fourth are y = 80/x
Put the values in and you will see the equations for yourself.
One
y = 80/2
y = 40
The 80 came from looking at this as an indirect variation. y = k/x
y = 40
x = 2
y = k/x
40 = k/2 Multiply both sides by 2
40 * 2 = k
k = 80
Two
y = k/x
20 = k/5
k = 20 * 5
k = 100

So sorry if what I solved is wrong .I did my best!
Answer:
Hi, The.
The domain of a function is the set of all possible values for x. The range is all possible values for y.
You should be able to see these pretty easily from the graph. If I understand your function correctly:
f(x) = square root(x+2) - 3
then x cannot be less than -2. Your domain is x > -2. In interval notation [-2,∞)
The lowest value for y is -3 so the range is y > -3. In interval notation [-3,∞)
Hope this helps!
