Please Help Me =( Let f(x) = –7x + 9. Suppose you add 2 to the input of f to create a new function g, then multiply the output of function g by –3 to create function h. What are the slope and y-intercept of the graph of function h?

slope = ?
y-intercept = ?

-21 = slope

-69 = intercept

Step-by-step explanation:

Given the function :

f(x) = - 7x +. 9

Suppose you add 2 to the input of f to create a new function g,

Add 2 to the input of f to create g

g(x) = f(x + 2) = 7(x +2) + 9

g(x) = 7x + 14 + 9

g(x) = 7x + 23

then multiply the output of function g by –3 to create function h.

h(x) = - 3(g(x)) = - 3(7x + 23)

h(x) = - 21x - 69

What are the slope and y-intercept of the graph of function h?

The slope and y intercept are :

From y = mx + c ; comparing the relation ;

Where m = slope ; c = intercept

m = - 21 = slope

c = -69 = intercept

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.
