Question: how to find the slope of the curve at a given point?
Answer: To find the slope m m m of a curve at a particular point, we differentiate the equation of the curve. If the given curve is y = f ( x ) , y=f(x), y=f(x), we evaluate d y d x \dfrac { dy }{ dx } dxdy​ or f ′ ( x ) f'(x) f′(x) and substitute the value of x x x to find the slope.
