Correct Answer

B. (x=2)

Step 1

Concept

The axis of symmetry passes through the midpoint of zeroes, \(\frac{-2+6}{2}=2\). Tip: the average of two zeroes is useful for a parabola.

Step 2

Why this answer is correct

The correct answer is B. (x=2). The axis of symmetry passes through the midpoint of zeroes, \(\frac{-2+6}{2}=2\). Tip: the average of two zeroes is useful for a parabola.

Step 3

Exam Tip

सममिति अक्ष शून्यकों के मध्य से गुजरता है, \(\frac{-2+6}{2}=2\)। टिप: परवलय में दो शून्यकों का औसत उपयोगी होता है।
