Practice problem
When is the function graphed above concave up? Concave down?
Concave up: (−∞,2.75)(-\infty, 2.75)(−∞,2.75)
Concave up: (3,∞)(3,\infty)(3,∞)
It is never concave up
Concave down: (−∞,2.75)(-\infty, 2.75)(−∞,2.75)
Concave down: (3,∞)(3,\infty)(3,∞)
It is never concave down
Type a concept, like “slope” or “photosynthesis”.
