For each of the functions below, identify the independent variable, the depen- dent variable, and all parameters. 1. Linear function: y = f(x) = 50x +5 2. Linear function: x = f(3) = By(2-1) 3. Linear function: a = f(y) = 20y + 5 4. Quadratic function: y = f(x) = -1 -5x - 3x Question 2. For each equation below: i) determine whether the equation can be expressed as a function y = f(x), where y is the dependent variable and r is the independent variable; ii.) briefly explain why. 1. y = 5/ 2. x = y + 3 3. x + y = 1 4. x = + 10
