, Name the property of an even function - Answers -f is even if and only if f(x) = f (-x) for
all x values in the domainEx. f(x) = x^2 --> f(4) = 16 --> f(-4) = 16 --> f(3) = 9

Name the properties of an odd function - Answers -1. f is odd if and only if f(-x) = -f(x)
for all x values in the domain
2. symmetrical with respect to the origin
3. whenever (x, y) is on the graph so is (-x, -y) as well

What is the form for a rational function and what is its domain and range? - Answers -
f(x) = P(x)/Q(x)Domain: all x values when Q(x) does NOT equal 0

Intermediate Value Theorem - Answers -If f is continuous on [a,b] and k is a number
between f(a) and f(b), then there exists at least one number c such that f(c)=k

Alternative Definition of a Derivative - Answers -(f(x)-f(c))/(x-c)


f '(x) is the limit of the following difference quotient as x approaches c

y' of uvw - Answers -uvw'+uv'w+u'vw

(dy/du)(du/dx) - Answers -(dy/dx)

Extreme Value Theorem - Answers -If f is continuous on [a,b] then f has an local
maximum and an local minimum on [a,b]. The local extrema occur at critical points in
the interval or at endpoints of the interval.

Critical Number - Answers -If f'(c)=0 or does not exist, and c is in the domain of f, then c
is a critical number. (Derivative is 0 or undefined)

Rolle's theorem - Answers -Let f be continuous on [a,b] and differentiable on (a,b) and if
f(a)=f(b) then there is at least one number c on (a,b) such that f'(c)=0 (If the slope of the
secant is 0, the derivative must = 0 somewhere in the interval).

Mean Value Theorem - Answers -f'(c) = (f(b) - f(a))/ (b - a)

First Derivative Test - Answers -When testing critical values, if the first derivative
changes from negative to zero to positive, then that critical value is a local minimum of
the function. If the first derivative changes from positive to zero of negative, then that
critical value is a local maximum of the function

Second Derivative Test - Answers -if f'(c) = 0 and f''(c) > 0 then minimum; if f'(c) = 0 and
f''(c) < 0 then maximum
