Answer:
Parent function f(x) = x with f(x)+5 means the parent function will vertically shift 5 units up.
Step-by-step explanation:
<u>Vertical translation of f(x) is of the form</u>
It means if the constant 'k' is added in the output, the parent graph vertically shifted 'k' units up.
Given
Replacing the parent function f(x) = x with f(x)+5 means the parent function will vertically shift 5 units up.
Please also check the attached diagram.
-
The red graph shows the parent function i.e.
- The blue graph shows the transformed function i.e. f(x)+5
The blue graph is the result of the vertically shifting of the parent function by 5 units up.
Hence, parent function f(x) = x with f(x)+5 means the parent function will vertically shift 5 units up.
I hope this helps!! Look at the top and the graph, don't know which answer you prefer :)
Answer: The correct option is
(C) 1 : 4.
Step-by-step explanation: Given that John ordered 4 pairs of black socks and some additional pair of blue socks. The price of the black socks per pair was twice that of the blue.
When the order was filled, it was found that the number of pairs of the two colors had been interchanged. This increased the bill by 50%.
We are to find the ratio of the number of pairs of black socks to the number of pairs of blue socks in the original order.
Let b represents the number of pairs of blue socks that John ordered and p be the price per pair of blue socks.
Then, the price of the black socks per pair = 2p.
The total price of the socks originally is
and the cost of the socks after interchange of the colors is
According to the given information, we have
So, there are 16 pairs of blue socks.
Therefore, the ratio of the number of pairs of black socks to the number of pairs of blue socks in the original order was
Thus, option (C) is CORRECT.
