H(x) = x² - 1
Over which interval does h have a negative average rate of change?

x < 0     Interval Notation: (-∞, 0)

Step-by-step explanation:

This is a parabola. The left side of the parabola has a negative rate of change and the right side of the parabola has a positive rate of change.

So it will have a negative rate of change for all x-values less than the Axis of Symmetry.

h(x) = x² + 0x - 1

     a=1   b=0  c=-1

It has a negative rate of change when x is less than 0

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
