Question

Identify two tables which represent quadratic relationships

Answer 1

Answer:

Tables 3 and 5

Step-by-step explanation:

if you know that quadratic equations from curves, then, check out the number patterns on 3 and 5, then, compare them with the others, you'll see

Answer 2

Answer:

Table 3 and 4

Step-by-step explanation:

Let us understand the coordinates symmetry of the graphs of quadratic equations.

In a quadratic equation, we have a polynomial in x with degree 2. Hence the result in y or P(x) do get repeated as polynomial contains $x^2$ in it.

Thus by analysing the tables we see that in table 3 , y= -10 gets repeated and in table 4 , y =4 and y=-4 repeated. Hence they are the graph of a quadratic polynomial
