CONTINUITY
The idea behind continuous functions is where a graph can be drawn without lifting a pen
off of the paper. A function whose graph is broken at a particular point is said to be
discontinuous at that point.
The reason

In algebra, we solve equations for a particular value of a variable; in calculus, we are
interested in how a change in one variable affects another variable. For example, how
does the length of skid marks change if we increase

The inverse of the exponential function, which is created by interchanging all x values with their
corresponding y values, is the logarithmic function.

Polynomial Functions:
f ( x) = an x n + an1 x n1 + an2 x n2 + . + a1 x + a0
Real number coefficients: a n , a n 1 , a n 2 , ., a1 , a0

Exponential Functions
b > 0, b 1
The equation f ( x ) = b x
defines an exponential function for each different constant b, called the base. The domain of f is
the set of all real numbers, and the range of f is the set of all p

All semester, we have been working with functions with one variable. Even when we
looked at implicit differentiation in Section 4.5, the second variable was considered a function of
the first variable.
We are now going to look

We will now consider a particularly powerful method of solving a certain class of maxima-minima
problems. The method of Lagrange multipliers is used to find an absolute extrema of a function that is
also limited by a second eq

Many of the indefinite integral formulas introduced in the preceding section are based on
corresponding derivative formulas studied earlier. We now consider indefinite integral formulas
and procedures based on the chain rule f

Finding absolute extrema is one of the most important applications of the derivative. We will be using
much of the material we learned in the first two sections of chapter 5.

Since the derivative is associated with the slope of the graph of a function at a
point, it can tell us a great deal about the shape of the graph of a function.

In the previous section we saw that the derivative can be used to determine when a graph
is rising and falling. Now we want to see what the second derivative (the derivative of
the derivative) can tell us about the shape of a

One important use of calculus in business and economics is in marginal analysis. We
introduced the concept of marginal cost earlier. There is no reason to stop there.
Economists also talk about marginal revenue and marginal pr
