Question

From the coordinate table for \[y = x^{2}\], what is the value of \[y\] when \[x = -2\]?

पर्याय

• \[9\]

• \[4\]

• \[-4\]

• \[2\]

Answer 1

For \[y = x^{2}\], substituting \[x = -2\] gives \[y = (-2)^{2} = 4\]. The table values of \[y = x^{2}\] are symmetric about the y-axis, so \[x = -2\] and \[x = 2\] both give \[y = 4\].
