A taste of what is inside
- What is the general equation of a linear or affine function?f(x) = a / xf(x) = ax² + bx + cf(x) = mx + cf(x) = x³
- What is the graph of an affine function?A circleA hyperbolaA parabolaA straight line
- Is a vertical line x = 3 considered a function f(x)?No, because one x has infinitely many y valuesNo, because x cannot equal 3Yes, a linear functionYes, an affine function with m=1
