1.3 Basic Functions

Identity Fn Squaring Fn Cubing Fn

Reciprocal Fn Square Root Fn Exponential Fn

Natural Logarithm Fn Sine Fn Cosine Fn

Absolute Value Fn Greatest Integer Fn Logistic Fn

f(x)=x f(x)=x2 f(x)=x3

f(x)= 1 x

f(x) = √x f(x) = e x

f(x) = ln x f(x) = sin x

f(x) = cos x

f(x) = x f(x) = int (x)

f(x) = 1

1 + e-x

Find the domain of each basic function.

• September 28, 2009

Which of the functions have points of discontinuity?

• September 28, 2009

Which functions are bounded (above and below)?

• September 28, 2009

Which functions are even?

• September 28, 2009

Graph the function: f(x) = sin (x) + 5

a. On what interval, if any, is the function increasing? decreasing?

b. Is the function odd, even, or neither?

c. Give the function's extrema, if any.

d. How does the graph relate to any of the 12 basic functions?

Piecewise Function: a function whose domain is divided into several parts and a different function rule is applied to each part.

f(x) = x2 if x ≤0 √x if x >0
