Capitalism is an economic system based on private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system, and competitive markets.
f(x) = (x+1)^1/2. Hi Carla, The derivative of $f(x)$ is the limit, as $h$ approaches zero of the difference quotient. \[\frac{f(x + h) - f(x)}{h}.\]. For your function this difference quotient is. \[\frac{(x + h + 1)^{1/2} - (x + 1)^{1/2}}{h}.\]. If you multiply the numerator and denominator by $(x + h + 1)^{1/2} + (x + 1)^{1/2}$ and simplify you will arrive at an expression that can be evaluated as $h$ approaches zero.
To summarize: D EFINITION 2.2. The limit of a function. We say that a function f(x) approaches a limit L as x approaches c if the sequence of values of x, both from the left and from the right, causes the sequence of values of f(x) to satisfy the definition of approaches a limit L: Definition 2.1.gain, when we say that the values of x approach a limit, that limit is never a value of x. There is always a difference between the values of x and their limit. The limit is the boundary beyond which no member of the sequence will pass. We summarize this in the following definition.
