A local maximum of the function f(x) occurs for which x-value?
f(x)
X
-4
-3
16
-2
-2
0
-1
6

- 4

Step-by-step explanation:

As per table the maximum value of the function is:

at x- value of:

So the correct answer option is -4

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
