what does f(a+h) represent on a point of a curve

The expression \( f(a+h) \) represents the value of a function \( f(x) \) at the point \( x = a + h \), where \( a \) is a specific point on the curve, and \( h \) is a small increment (or change) from that point.

In the context of curves, particularly when talking about calculus and derivatives:

1. **At \( x = a + h \)**: The point on the curve is determined by the value of the function at \( a + h \), which means \( f(a+h) \) gives the height or \( y \)-value of the curve at that \( x \)-coordinate.

2. **When \( h \) is small**: If you're dealing with limits and derivatives, \( f(a+h) \) is used to explore the behavior of the function as you move slightly away from \( a \). For instance, when finding the derivative, you compute how much the function changes between \( f(a) \) and \( f(a+h) \) as \( h \to 0 \).

This is essential for calculating the slope of the tangent line at a point \( a \), using the formula for the derivative:

\[
f'(a) = \lim_{h \to 0} \frac{f(a+h) - f(a)}{h}
\]
