What are the x-coordinates of the intercepts of the function \(f(x)=-(x-1)^2+4\) on the x-axis?

Answer and explanation

Correct answer: \(x=-1\) और \(x=3\)

At every point on the x-axis, \(y=f(x)=0\). Thus, \(-(x-1)^2+4=0\), which gives \((x-1)^2=4\). Therefore, \(x-1=\pm2\), so \(x=-1\) or \(x=3\). Hence, option A is correct. Remember that the complete intercept points are \((-1,0)\) and \((3,0)\); this question asks only for their x-coordinates.
