Question

Which is the function represented by the table? A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, negative 1, 0, 1. Column 2 is labeled f (x) with entries negative 8, negative 4, 0, 4.

Answer 1

Answer:

$f(x)=4x$

Step-by-step explanation:

Given: See the attached image

To find: the function represented by the table

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

$f(-2)=-8=4(-2)\\f(-1)=-4=4(-1)\\f(0)=0=4(0)\\f(1)=4=4(1)$

Here, $-2,-1,0,1$ are elements in the domain and $-8,-4,0,4$ are elements in the co-domain.

Therefore, the table represents the function $f(x)=4x$
