If f(x)= 3x-4, find f(-2) - f(3)​

-15

Step-by-step explanation:

f(-2) = 3(-2) - 4 = -6 - 4 = -10

f(3) = 3(3) - 4 = 9 - 4 = 5

f(-2) - f(3)​ = -10 - 5 = -15

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.
