Question

Is y= 0.25 + 0.5(x-2) linear or non linear?

And this equation also
Y= x(3-x)+ 1

Answer 1

it is non linear

Explanation:

Answer 2

Explanation:

Because x and y here both have the exponent 1, we know that y= 0.25 + 0.5(x-2) is linear.

Expanding Y= x(3-x)+ 1, we get y = 3x - x^2. Because the highest power on the independent variable (x) is 2, this equation is quadratic (not linear).
