See attachment 1st

Answer 2

Question 1: What is the value of f"(4)?
Question 2: Is f(x) increasing or decreasing at x=2? Explain how you know
Question 3: What is the value of f(2)?
Question 4:Besides possibly at the endpoints of its domain where does f(x) have its relative minimum values? Explain how you know.
Question 5: Where does f(x) have its absolute minimum value? Explain how you know

Answer 3

@Mertsj can you please help me I am new

Answer 4

@satellite73 can you please help me I am new and I have no idea what is going on

Answer 5

can you please help

Answer 6

That is a picture of the first derivative of the function f

Answer 7

ok I am really confused and my teacher is not very good so what ever you say I am going to take notes and learn

Answer 8

You do know that is the graph of the first derivative, right?

Answer 9

yes

Answer 10

are you still there @Mertsj

Answer 11

You're the one who disappeared and wouldn't answer.

Answer 12

I said yes that I understood that that was what it was

Answer 13

what next?

Answer 14

At x = 4, the graph of the first derivative is a line. Its slope is -2 and its y intercept is 7. So its equation is y = -2x+7.

Answer 15

ok

Answer 16

Taking the derivative of the first derivative gives us the second derivative. It is f"=-2...a constant function. So the f"(4)=-2

Answer 17

oh ok gotcha

Answer 18

The first derivative is positive at x = 2 so the function f is increasing.

Answer 19

ok

Answer 20

so then what is next

Answer 21

I'm not sure about the f(2). Have to refresh my memory on that.

Answer 22

ok

Answer 23

Where the first derivative is 0 are the points where the slope of the tangent is 0 and they correspond to relative minima or maxima. So that would be 3.5 and 7

Answer 24

sorry but the last post you did what question does that go along with
