Algebra - Operations of Functions and Domains

For the given functions f and g, find the following functions and state the domain of each. (a) f + g  (b)f - g  (c)f x g  (d) f / g f(x) = 2xsquared + 3; g(x) = 4xcubed + 1

Algebra - Functions and Domains

For the given functions f and g, find the following functions and state the domain of each. (a) f + g   (b)f - g  (c)f x g  (d) f / g f(x)= square root of x + 1;  g(x) = 2 / x

Algebra - Composition of Functions

For the given functions f and g, find: (a)  the composition of (f o g) (4) (b) (g o f) (2)  (c)( f o f) (1)  (d) (g o g) (0) f(x) = 2x; g(x) = 3xsquared + 1

Algebra - Composition

For the given functions f and g, find: (a) the composition of (f o g) (4)  (b) (g o f) (2)  (c)( f o f)(1)   (d) (g o g) (0) f(x) = x3/2; g(x) = 2 / x + 1  *note: x3/2 is actually a square root number but I couldn't figure out how to make the numbers small.
