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
