❖ Adding and Subtracting Functions - Function Notation ❖

Adding and Subtracting Functions - Function Notation. In this video I show how to evaluate a function using function notation by evaluating f(4). I also show function notation and show how to add/subtract the functions: f(x) = x^2 + 2x + 8 and g(x) = 3x^2 - x + 7 by distributing and collecting like terms. #math #algebra #khanacademy #khan #geometry #education #montessori #homeschooling #functions #notation #organicchemistry #organicchemistrytutor
