The function f(x) = StartRoot negative x EndRoot is shown on the graph. On a coordinate plane, an absolute value graph starts at (0, 0) and goes up and to the left through (negative 4, 2).

Which statement is correct?
The domain of the function is all real numbers greater than or equal to 0.
The range of the function is all real numbers greater than or equal to −1.
The range of the function is all real numbers less than or equal to 0.
The domain of the function is all real numbers less than or equal to 0.

-2 is the right

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
