Question

*** WILL FAN AND MEDAL***


Using complete sentences, explain how to find the minimum value for each function and determine which function has the smallest minimum y-value.


f(x) = 3x2 + 12x + 16
g(x) = Following graph

Answer 1

@Mehek14 @Preetha pLEASE HELP ME!

Answer 2

for the first question, have you tried factoring?

Answer 3

No, not really but I'll try it right now:

Answer 4

wait

Answer 5

to save some time, i checked and it doesn't factor

but no worries

Answer 6

Oh ok

Answer 7

I dont understand how Im supposed to find the minimum.... I didn't understand that part of the class..

Answer 8

Oh okay well when that is solved it comes up to: - 10.66667

Answer 9

I think...

Answer 10

let's try this formula instead

Answer 11

x = -b/2a

Answer 12

(the other one was for a different form)

Answer 13

x = -12/2(3) = -2

Answer 14

now, just calculate f(x) = 3x2 + 12x + 16 for x = -2

Answer 15

oh ok so it would be -2

Answer 16

(nope not -2)

Answer 17

(-2 is the x value)

Answer 18

oh no nvm I got it: It would go to:

40

Answer 19

@Vocaloid

Answer 20

nope

Answer 21

3x2 + 12x + 16 = 3(-2)^2 + 12(-2) + 16 = ?

Answer 22

4?

Answer 23

@Vocaloid

Answer 24

good so the minimum is 4

Answer 25

for g(x), what's the lowest y value on the graph?

Answer 26

The lowest y-value is (pi / 2, -2)

Answer 27

good!

so the minimum of f(x) is (-2,4) and the minimum of g(x) is (pi/2, -2)

and that's your answer

Answer 28

Oh, ok , thats it?

Answer 29

Thank you so much!!
