Exercise 5.7.11 Describe the concavity of the functions below. (a) y=x²-x (g) y = 3x² − (1/x²) (b) y=2+3x-x³ (h) y sinx | cosx (c) y = x³ − 9x² +24x (i) y = 4x+√1-x (d) y=x²-2x²+3 (e) y = 3x4-4x²³ (†) y = (x² − 1)/x (j) y = (x+1)/√√5x² +35 (k) y = x - x (1) y = 6x + sin 3x (m) y=x+1/x (n) y = x² +1/x (o) y = (x+5) ¹/4 (p) y = tan²x (q) y = cos²x-sin²x (r) y = sin³x
