What is the slope of the tangent to y = x^2 at x = 7?
वक्र y = x^2 पर x = 7 पर tangent की slope क्या होगी?
Show answer and explanation
Correct Answer
A. 14
ExplanationStep 1: The slope of a tangent is found using the derivative. Step 2: dy/dx = 2x, so at x=7, slope = 2×7 = 14. Step 3: When slope is asked, find the derivative first.
Step 1: Tangent की slope derivative से मिलती है। Step 2: dy/dx = 2x, इसलिए x=7 पर slope = 2×7 = 14। Step 3: Slope पूछे तो पहले derivative निकालें।
