The domain of a quadratic function is all real numbers
Answer:
Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600
Step-by-step explanation:
- ∴ S = L - 20% L
- ∴ S = 0.8 L ..... (1)
- ∴ S = P + (1/3)P
- ∴ S = (4/3) P ..... (2)
- As we know, P = 1200
- ∴ S (4/3) × 1200
- ∴ S = Rs. 1600
- 1600 = 0.8L
- ∴ L = 1600 ÷ 0.8
- ∴ L = Rs.2000
- ∴ Lebeled Price of watch = Rs. 2000
- Selling price pf the watch = Rs. 1600
Answer:
Step-by-step explanation:
Because we have to rewrite this equation in the format 
, we have to divide, or factor to find basic terms,
Expanding the value of k(x), we have 
. We see that each term can be divisible by 4, so we can factor out 4 to get
Now, we have two different terms getting multiplied. We can separate the two to get 
Because we are multiplying 4 by the other term, this is represented by 
Now, we can just set f(x) and g(x) to these functions:
Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.
Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).
Answer:
You will want to add up the total for all four guests (The one after you added the tip) and then since you want to split it evenly, you can multiply it by 1/4.
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
