Find the points of inflection of the graph of the function. (If an answer does not exist, enter DNE.)
f(x) = 2 sin x + 2 cos x, [0, 24]
(x, y) = (4.0
(smaller x-value)
(x, y) = (0
(larger x-value)
Describe the concavity. (Enter your answers using interval notation.)
concave upward
DNE
concave downward

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
