1. Use the word box to answer the question increasing decreasing point of inflection y-values concave up critical point
zeros slopes positive relative extrema concave down negative

a. () has a relative maximum when f′(x) changes from to .
b. Points of inflection on f(x) are on the graph of ′().
c. When f′′(x) is , f(x) is concave down.
d. When f′(x) is increasing, f(x) is and f′′(x) is .
e. An x-intercept on f′(x) corresponds to a of f(x).
f. When f′(x) is positive, f(x) is .
g. The of f′(x) give the slopes of f(x).
h. When f′(x) changes signs, f(x) has.
i. When the of f(x) are decreasing, f′′(x) is negative.
