The values in the table represent a function.

Hatshy [7]

Given:

The values in the table represent a function.

x f(x)

-2 1

1 3

4 -2

-3 0

0 4

To find:

Function notation for the ordered pair given in the first row in the table.

Solution:

We know that, if a point (a,b) is on the function, then $f(a)=b$ .

From the given table, the ordered pair given in the first row is (-2,1). So,

$f(-2)=1$

Therefore, $f(x)=1$ when $x$ is $-2$ .

Use benchmarks to estimate 16.8-5.94

Sunny_sXe [5.5K]

The estimated answer is 11. First you round 16.8 to 17 because the decimal is above 5. Then you round 5.94 to 6 because the first decimal place is greater than 5. Lastly you subtract 17 minus 5 to get 11.
