Figure out the output for 1 and 2 and figure out if their linear or nonlinear

Step-by-step explanation:

Simply plug each x value into the equation

1.

-3, 0, 3, 6, 8, yes it is linear, it doesn't have any exponents

2.

Same thing

5,2,1,2,5, it has exponenets and is not linear

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
