Algebra II Exercise: Operations with Functions

By B Horn

Directions and/or Common Information:



f(x) = 2x      g(x) = x - 2

h(x) = x2     k(x) = x/2

Use the functions above to perform the following operations:

k(x) ● f(x)

g(x) - h(x)

f(x) - k(x)

h(x) + k(x)

h(x) ● g(x)

f(x) ÷ k(x)

g(x) ● h(x)

f(x) + g(x)

Directions and/or Common Information:



f(x) = 2x      g(x) = x - 2

h(x) = x2     k(x) = x/2

Use the functions above to evaluate the following composite functions:

h[f(0)]

f[g(2)]

g[h(5)]

h[k(4)]

k[f(3)]

f[k(-2)]

g[g(-3)]

g
