For the function f(X) = -(X +1)+ 4, identify the vertex, domain, and range. The vertex is (-1, 4), the domain is all real numbers, and the range is y 2 4. The vertex is (-1, 4), the domain is all real numbers, and the range is y S4. The vertex is (1, 4), the domain is all real numbers, and the range is y 24. The vertex is (1, 4), the domain is all real numbers, and the range is y s4.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

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.
