To identify the function that contains the data in the table, we should first visualize the data.
A graph of the data is shown below:
From the plot above, we can identify that:
The graph above is a graph of f(x) = |x|, translated to the right 2 units and translated upwards 1 unit.
Hence, the function is:

Answer:
Option D
Answer:
c
Step-by-step explanation:
Answer:
x has no real solution
Step-by-step explanation:
Our equation is qudratic equation so the method we will follow to solve it is using the dicriminant :
- Let Δ be the dicriminant
- a=1
- b=2
- c=9
- Δ= 2²-4*1*9 =4-36=-32
- we notice that Δ≤0⇒x has no real solution
Answer:
It will take him <u>20 days</u> to read a 300-page book.
Step-by-step explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in =
days.
Thus, Stephen read 300 page in = 


Therefore, it will take him 20 days to read a 300-page book.
