Question

A function which gives the slope of a curve; that is

Answer 1

Tangent

Step-by-step explanation:

• The slope of a curve at a point is equal to the slope of the straight line that is tangent to the curve at that point.
• The slope of a curve y = f(x) at the point A means the slope of the tangent at the point A.
• Tangent of a curve tells us the rate of change at a particular instant.
• We write y = f(x) on the curve since y is a function of x. That is, as x changes, y also changes.
