Question

using complete sentences explain how to find the minimum value for each for each function and and determine which function has the smallest y value

Answer 1

f(x) = 3x^2 + 12x + 16
And
g(x) = 2sin (2x-pi) +4

Answer 6

dont u graph it and see the amplitude and midline

Answer 7

ok, may be you are not cal student. I make another question: for f(x), it is an upward parabola, right? so, its min is its vertex, what is it? ( I mean coordinate of the vertex)

Answer 8

hmmm

Answer 9

not suree

Answer 10

hmmmmm means "don't know", right?

Answer 11

lol, x-coordinate is -b/2a =??

Answer 12

Yess

Answer 13

=? , number, please

Answer 14

oh sorry haha ok so

Answer 15

wow i havent done that in a while.. Is it 16

Answer 16

nope, ax^2 +bx+c , your case 3x^2+12x +16, so a =3, b =12 c =16 ( but we don't use c, let it aside) so that what is -b/2a?

Answer 17

-12/6

Answer 18

=??

Answer 19

2

Answer 20

nope, you forgot the - sign, redo

Answer 21

-2?

Answer 22

ok, now we have x-coordinate of the vertex, plug x =-2 into f(x) , what do you get?

Answer 23

-4

Answer 24

it's not correct, show me your work so that I can see what 's wrong

Answer 25

3(-2)^2 +12(-2) + 16

Answer 26

-6^2 -24 + 16

Answer 27

36-24+16

Answer 28

hihihih 3(-2)^2 = 3*4 =12, it's not -6^2. You must square the number inside the bracket first, then time 3 from the out side

Answer 29

so, it is 12 -24+16 =-4

Answer 30

So far, from f(x) you have the vertex (-2,-4) right?
