What can a Linear Function Equation be written as? - answersf(x) = ax + b or f(x) = mx + b. The formula for a quadratic function is different from that of a linear function because it contains an x^2 term. Examples: f(x) = 3x^2 + 3x + 5 and g(x) = 5 - x^2 are not linear equations because of the ^2's. What is the Quadratic Function Equation? - answersThe "a" in f(x) is called the Leading Coefficient. What is a Parabola? - answersThe graph f(x) is called a Parabola. Exampl...
