1) Graph these functions using a graphing calculator or program:
f(x) = x^2 + 5
g(x) = 2x + 5
h(x)= x^3 + 5
What similarities and differences can you see among them?
2) Given the above functions, do you think that all linear equations can be expressed as functions?
What similarities and differences might there be between functions and linear equations? Are all linear equations functions?
