Use the graph of f to estimate the local maximum and local minimum. (5 points)

(A) maximum = (0, 1), minimum = (, -1) and (-π, -1)

Step-by-step explanation:

The maximum is the highest point on the graph.  Which is the vertex of a negative (upside down) parabola.

The minimum is the lowest point on the graph. Which is the vertex of a positive (u-shaped) parabola.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
