फलन \(y=x^2-4\) का ग्राफ (x)-अक्ष को किन बिंदुओं पर काटता है?

At which points does the graph of \(y=x^2-4\) cut the (x)-axis?

Explanation opens after your attempt
Correct Answer

A. ( \left\(-2,0\right\),\left\(2,0\right\) )

Step 1

Concept

Set (y=0) on the (x)-axis. From \(x^2-4=0\), \(x=\pm 2\).

Step 2

Why this answer is correct

The correct answer is A. ( \left\(-2,0\right\),\left\(2,0\right\) ). Set (y=0) on the (x)-axis. From \(x^2-4=0\), \(x=\pm 2\).

Step 3

Exam Tip

(x)-अक्ष पर (y=0) रखें। \(x^2-4=0\) से \(x=\pm 2\) मिलता है।
