The question
Question: what is the largest value of f in this table of f?
largest value of f = ?
1 Look at the table
The table shows f.
Each x on top has its f(x) right under it.
For example, f of 1 is 6.
x: top row
f(x): right under its x
2 Find the biggest value
The values of f are the numbers in the f(x) row.
We look for the biggest one.
largest value of f → the top of the f(x) row
Careful!
The value of f is a number in the f(x) row.
We answer with it, not with the x.
Careful: the value is f(x), not the x
The f(x) row is 6, 2, 5, 9 and 4.
The biggest is 9.
So the largest value of f is 9.
It is at x = 4.
largest value = 9
3 Check
Let's check: in the f(x) row, no number is bigger than 9.
So the answer is right!
f(x) row: 6, 2, 5, 9, 4 biggest: 9
Let's look back.
First: look at the table.
Then: find the biggest value.
Last: check.
Answer
largest value = 9
