how do I show the value of y = 2x for values of x from -2 to 2​

Step-by-step explanation:

If you are looking for values of y, they are:

  • y = 2x
  • x = - 2 ⇒ y = 2*(-2) = - 4
  • x = - 1 ⇒ y = 2*(-1) = - 2
  • x = 0 ⇒ y = 2*0 = 0
  • x = 1 ⇒ y = 2*1 = 2
  • x = 2 ⇒ y = 2*2 = 4

Show the value of y=2x for values of x from -2 to 2

  • The question is asking us to substitue x with all the values that come between -2 and 2

The numbers between these numbers are:

-2,-1,0,1,2

Now, Substitute all these values on by one and solve for x

x = -2

[tex]y = 2x \\ y = 2 \times ( - 2) \\ y = - 4[/tex]

x = -1

[tex]y = 2x \\ y = 2 \times ( - 1) \\ y = - 2[/tex]

x = 0

[tex]y = 2x \\ y = 2 \times 0 \\ y = 0[/tex]

x = 1

[tex]y = 2x \\ y = 2 \times 1 \\ y = 2[/tex]

x = 2

[tex]y = 2x \\ y = 2 \times 2 \\ y = 4[/tex]
