Question

The table represents a function.

A 2-column table with 4 rows. The first column is labeled x with entries negative 4, negative 1, 3, 5. The second column is labeled f of x with entries negative 2, 5, 4, negative 8.
What is f(5)?

–8
–1
1
8

Answer 1

Answer:

-8

Step-by-step explanation:

You are given the following table representing the function f(x):

$\begin{array}{cc}x&f(x)\\-4&-2\\-1&5\\3&4\\5&-8\end{array}$

This means

$f(-4)=-2\\ \\f(-1)=5\\ \\f(3)=4\\ \\f(5)=-8$

Hence,

f(5)=-8

Answer 2

Answer:

-8

Step-by-step explanation:

The given table is

x     f(x)

-4    -2

-1      5

3      4

5     -8

So, when we express $f(5)$, it refers to the image assigned for $x=5$.

In the given table, you can observe that they image assigned to $x=5$, it's $-8$. In other words,

$f(5)=-8$

Because the given table represents a function that relates $y=-8$ to $x=5$.

Therefore, the right answer is the first choice -8.
