WebThis means that you can choose to say that a straight line is concave up or concave down. A straight line f ( x) = m x + b satisfies the definitions of both concave up and concave because we always have f ( t a + ( 1 − t) b) = t f ( a) + ( 1 − t) f ( b) . Example: y = − 2 x + 1 is a straight line. It is both concave up and concave down.
