Question

ALGEBRA 2, UNIT 3, LESSON 5:
Graphing Quadratics
ALTERNATE ASSIGNMENT

Did you know parabolas are all around you in the real world!? If you’ve traveled to the Midwest, you may have seen this one before:
The Gateway Arch in St. Louis, Missouri is a 630-foot high monument that was first designed in 1947. Construction of the stainless steel arch lasted many years, and the arch was not completed until October 1965. It was created as a monument to the westward expansion of the United States, and to this day it is the tallest man-made monument in America, as well as the world’s tallest arch

Answer 1

Use the following function to complete #1-3 below f(x)=2(x-6)^2+4

1) Using complete sentences, explain how to convert f(x) into standard form.
Give the final standard form equation in your answer.

2) Graph f(x) by hand or with technology. Include a photo or screenshot of the parabola.

3) Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Answer 2

please help will medal and fan i beg of yall lol

Answer 3

Hun I honestly would help but I took this stuff back in 9th grade I can't even remember any of it

Answer 4

Answer 7

GUYS PLEASE HELP ME I AM LIKE LITERALLY BEGGING YALL

Answer 8

lik i know the standard form of the porabola is y=2x^2-27x+76 which is #1

Answer 9

so i mean i can explain tht but idk how to do #3

Answer 10

@mathmath333 @magepker728

Answer 11

do you know the slope of the line...?

Answer 12

@morganchavez

Answer 13

no but i can try n find it :)

Answer 14

ok, average rate of change will be average rate of change = [f(7) - f(4)] / (7 - 4) ...

Answer 15

?

Answer 16

um ok so lik vertex means slop right ?

Answer 17

yup

Answer 18

ok so the slope is (6,4)

Answer 19

right ?

Answer 20

agree

Answer 21

like y do i need the slope ? like what number?

Answer 22

slope is equal to the average rate of change...

Answer 23

like im so sorry paki but im so confused n i dont know y

Answer 24

ok so how would i write it out then ?

Answer 25

im so sorry im a visual learner im not trying to make u do my work i swear i jus need help my teacher on flvs doesnt explain nothing n ive been on this for 4 days now

Answer 26

rite... so you need all these basics from the start i think.... @morganchavez

Answer 27

yes please if u dont mind please

Answer 28

well lik not the very beginging jus the part where the average rate part starts

Answer 29

where you have the problem...?

Answer 30

lik #3 like where n how i put tht equation togehter with the slop n stuff

Answer 31

ok... please have a look here...

Answer 32

ok thx

Answer 33

pleasure...

Answer 34

y1=2(7-9)2+17

y2=2(4-9)2+17 right ?

Answer 35

@paki so now i jus solve them and by solving i mean simlify right ?
