a. The graph is concave up in the interval 0 ≤ x ≤ +∞
b. The graph is concave down in the interval -∞ ≤ x ≤ 0
To answer the question, we need to know what intervals are
<h3>What are intervals?</h3>
Intervals are range of values in which a function is valid. It can either be the range of values of input or output of the function.
<h3>a. Interval where the graph is concave up</h3>
From the graph, we see that the function is concave up in the interval 0 ≤ x ≤ +∞
So, the graph is concave up in the interval 0 ≤ x ≤ +∞
<h3>b. Interval where the graph is concave down</h3>
From the graph, we see that the function is concave down in the interval -∞ ≤ x ≤ 0
So, the graph is concave down in the interval -∞ ≤ x ≤ 0

Answer:
C 60 inches
Step-by-step -
60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.
Answer:
12
Step-by-step explanation:
6 pints in total
2 cups = 1 pint
2 cups = 1 pint
2 cups = 1 pint
2 cups = 1 pint
2 cups = 1 pint
2 cups = 1 pint
add all the 2s
the answer is 12
Since
, and we know that
, we then also know that
.
Recall that
We take the positive root because we know that
. Then
Now,
From Smallest to Largest is :
,7/10,2/5,and 1/8
