Answer:
The domain of the function is R i.e. any real value.
Step-by-step explanation:
The given figure is a graph on the coordinate plane of the function
Now, the domain of a function means that the values of x (Independent variable) for which the function is valid i.e. the y values are real.
It is clear from the equation given above that for any real value of x there will be a real corresponding value of y.
Therefore, the domain of the function is R i.e. any real value. (Answer)
Answer:
B
Step-by-step explanation:
So, to figure this out, we must find the total miles Maria ran in a week.
We know that she ran 2.75 miles each day.
She did this for 7 days.
Her goal was 17.5 miles.
So first, multiply the amount of days by the amount of miles per day:
7*2.75
=
19.25
So now we know that she ran a total of 19.25 miles in a week.
Since she onlu needed to run 17.5 miles, we can instantly rule out:
A - Runs less 17.5 miles
C - Runs exactly 17.5 miles
This leaves:
B - She runs 1.75 miles more than 17.5 miles
D - She runs 2.75 miles more than 17.5 miles
To figure out which on is correct, subtract her total miles by her goal:
19.25-17.5
=
1.75
So we know it must be:
B - She runs 1.75 miles more than 17.5 miles
This is because we figured out she ran an extra 1.75 miles.
Hope this helps! :)
