Step-by-step explanation:
given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website
The data is shown below:
Frequency Frequency*Midpt
Midpt Online Total Online Total
1-3 2 40 147 80 294
4-6 5 60 103 300 515
7-9 8 15 32 120 256
10-12 11 5 18 55 198
120 300 555 1263
Thus we find total items purchased on line = 555
and total items overall purchased = 1263
Hence the probability that a randomly selected item was purchased online
=
Answer:
we conclude that g(x) = f(x – 2) + 3 means the graph of g(x) is shifted 2 units right and 3 units up.
Option A is correct
Step-by-step explanation:
To shift a function right
- Subtract inside the function's argument. For example,
is basically
shifted b units to the right.
- Subtracting inside the function's argument moves you to the right.
So, g(x) = f(x – 2) means f(x) is shifted two units to the right.
and to move a function up
- Add outside the function. For example,
is basically
units.
So, g(x) = f(x – 2) + 3 means, f(x) is moved 3 units up.
Therefore, overall, after two transformations, we conclude
that g(x) = f(x – 2) + 3 means the graph of g(x) is shifted 2 units right and 3 units up.
So, option A is correct.
