Practice problem
When is the function graphed above concave up? Concave down?
Concave up: (−0.5,2.5)(-0.5, 2.5)(−0.5,2.5)
Concave up: (−∞,1)(-\infty,1)(−∞,1)
Concave up: (1,∞)(1, \infty)(1,∞)
Concave down: (−∞,1)(-\infty,1)(−∞,1)
Concave down: (1,∞)(1, \infty)(1,∞)
Concave down: (−0.5,2.5)(-0.5, 2.5)(−0.5,2.5)
Type a concept, like “slope” or “photosynthesis”.
