Practice problem
When is the function graphed above concave up? Concave down?
Concave up: (−3.75,−2)(-3.75, -2)(−3.75,−2)
Concave up: (−2,∞)(-2,\infty)(−2,∞)
Concave up: (−∞,−2)(-\infty, -2)(−∞,−2)
Concave down: (−2,∞)(-2,\infty)(−2,∞)
Concave down: (−∞,−2)(-\infty, -2)(−∞,−2)
It is never concave down
Type a concept, like “slope” or “photosynthesis”.
