Explanation opens after your attempt
C. ((5,0))
Concept
Putting (y=0) gives (4x=20), so (x=5). This is the vertex on the (x)-axis.
Why this answer is correct
The correct answer is C. ((5,0)). Putting (y=0) gives (4x=20), so (x=5). This is the vertex on the (x)-axis.
Exam Tip
(y=0) रखने पर (4x=20) इसलिए (x=5)। यह (x)-अक्ष पर बनने वाला शीर्ष है।
