Question

Write a function rule for the table.

f(x)
2
–8
3
–12
4
–16
5
–20

Answer 1

are those alternating x and y values?

Answer 2

^CHECK THAT OUT

Answer 3

if
f(2)=-8
f(3)=-12
f(4)=-16
f(5)=-20
The values are changing linearly so we know that the function has a rule of the form
f(x) = cx
f(2)=2x=-8
x=-4
thus the rule for the function x is to multiply x by negative 4

Answer 4

looks like
\[f(x)=-4x\]

Answer 5

Is it A or C?

Answer 6

A.
