Question: Graph the equation and see if its linear or not.

Answer 1

If we just look at the function we can infer that this equation is nonlinear since it has a variable with and exponent (x^2), so from the start we know it is not linear.

Now, solving for the values given, we complete the table:

x = -2 => y = 5

x = -1 => y = 2

x = 0 => y = 1

x = 1 => y = 2

x = 2 => y = 5

Now in the graph mode:
