Question

1. $f(x)=2x$

x

y

|-1|
|0|
|1|
|2|
|3|
parent function: ____

Explanation:

Step1: Substitute x = -1

$y = f(-1)=2\times(-1)= - 2$

Step2: Substitute x = 0

$y = f(0)=2\times0 = 0$

Step3: Substitute x = 1

$y = f(1)=2\times1=2$

Step4: Substitute x = 2

$y = f(2)=2\times2 = 4$

Step5: Substitute x = 3

$y = f(3)=2\times3=6$

Answer:

x	y
0	0
1	2
2	4
3	6

The parent - function is $y = x$.
