NEED HELP ASAP If f(x)= 4^x-1 and g(x)= 2x-5, what is (f - g) (x)?

A. (f - g) (x)=4^ x-1 -2x+1
B. (f - g) (x)= 4^ x-1 -2x-11
C. (f - g) (x)= 4^ x-1 -2x+11
D. (f - g) (x)=4^ x-1 -2x-1

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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.
