Question

Is
X 0 5 10 15
Y 0 25 100 225
Proportional or non proportional?

Answer 1

non proportional

Explanation:

From the table;

0 = 0

25 = 5^2

100 = 10^2

Since the y values are the output and x is the input, hence;

y = x²

Since the equation is quadratic, hence the table is non proportional
