  • Answer:

    not linear

    Step-by-step explanation:

    a linear function contains x and y only with the exponent 1.

    this allows the function to be a line (hence the term "linear"), a constant ratio of y changes to x changes for any values of x which defines linear relation between x and y.

    but this equation contains a term with x², which changes the size of change of y for every value of x.

    e.g. when x changes by 1 from 1 to 2, y changes by 3 from 1² to 2² (1 to 4). but if x changes again by 1 from 2 to 3, y changes by 5 from 2² to 3² (4 to 9).

    this is clearly not constant.
