Definition

A constant function is a function where the output value remains the same for every input value. In other words, it is a horizontal line on a graph.

Derivative:

The derivative of a function represents its rate of change at any given point. It measures how the output values change with respect to the input values.

Slope:

The slope of a line represents its steepness or incline. For a constant function, the slope is always zero because there is no change in the output values.

Tangent Line:

A tangent line touches a curve at only one point and has the same slope as that point on the curve. For a constant function, the tangent line is horizontal since the slope is zero everywhere.
