There's a lot of ways! So, you can plug in and solve, solve for the two roots, solve for the vertex form, and solve for the standard form. Multiple ways!
Answer:
Step-by-step explanation:
A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).
From the table attached,
For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).
Therefore, data given in the table doesn't represent a function.
