Determine whether the given function is linear. If the function is linear, express the function in the form f(x) = ax + b. (If the function is not linear, enter NOT LINEAR.) f(x) = 6x 7/ x Solution f(x) = 6x 7/ x is not a linear function due to presence of hyperbolic part in it ...that is 7/x ..which is making this function non-linear..
