State whether each function is a linear function. Write yes or no. Explain. ? 1.? SOLUTION:?? A linear function is a function with ordered pairs that satisfy a linear equation of the form y = mx + b. The function ?is?linear?as?it?can?be?written?as? . ANSWER:?? Yes; it can be written as 2.? SOLUTION:?? A linear function is a function with ordered pairs that satisfy a linear equation of the form y = mx + b. ?cannot?be?written?in?the?form?f (x) = mx + b. ? So the function is not linear. ANSWER:?? No; it cannot be written as f (x) = mx + b. 3.? SOLUTION:?? is not a linear function as x has an exponent that is not 1. ANSWER:?? No; x has an exponent that is not 1. 4.? SOLUTION:??
