I'm sorry but I can only answer number 2 the answer is 80 ounces
Hope this helps! Sorry if it doesn't.
Answer:
x is less than or equal to 16
Step-by-step explanation:
- 2 x x + 4 < 20
Isolate the variable
divide 2 from 2 = 0
x + 4 < 20
x is less than or equal to 16
The original function is
f(x)=√x
As this is condition for √x function, x≥ 0
So,
Domain= [0, infinity)
Range= [0, infinity)
After the reflection across x-axis and y-axis, we get a function,
g(x)=-√-x
-x≥ 0 means x≤ 0,
So,
Domain= (-infinity, 0]
Range= (-infinity, 0]
From this you can see that
-The only value that is in the domains of both functions is 0.
-The range of g(x) is all values less than or equal to 0.
only these points are correct and all other points are wrong.
See the attached graphs for both functions.
