Answer 2

Your answer ?

Answer 3

IM thinking G(x)

Answer 4

No.

f(x) is the right answer. Can you tell me the minimum value of each function ?

Answer 5

Minimum for g(x) is -2 , h(x) is -2, and im not sure about f(x)

Answer 6

First of all, the minimum value of g(x) is right. Next, for h(x), the value of a function is usually denoted by y. So, what's the minimum value of h(x) ?

Answer 7

3

Answer 8

Good

Answer 9

Now, for f(x) its a little bit tricky part. See, the higher the value of sin(2x - pi), the value of f(x) will become lesser. Do you get this ?

Answer 10

Its because we are multiplying sin(2x- pi) by a negative number.

Answer 11

Yes

Answer 12

Good now what's the maximum value of any sine function ?

Answer 13

I mean to say what's the maximum value of sin(2x-pi) ?

Answer 14

Ummm is it -1 to 1 ?

Answer 15

thats what sins can be

Answer 16

Yes

Answer 17

So, maximum value of sin(2x-pi) would be 1.

Answer 18

Ohhhh

Answer 19

Thus, minimum value of f(x) = -5 * 1 + 2 = -3

Answer 20

I see

Answer 21

So thats why it was f(x)

Answer 22

Yeah

Answer 23

Thank you! Thats all that I have for now I really appreciate it

Answer 24

No problem and best of luck

Answer 25

Good day
