The function f(2) is graphed below.
1J
Which of the following defines the function f(x)?
f(x) = 2 + k, where k = -3
f(x) = x + k where k= 3
f(3) = 2hwhere h = -3
Cf(x) = ls -h where h=3
Help pleaseee

the f

last graph i believe

worked it out i believe

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.
