Answer 1

3

Answer 2

May I help?

Answer 3

yes please

Answer 4

Thank you.

Answer 5

If we are given a function (of any form), its slope is equal to its first derivative.
ok?

Answer 6

but its not one of the choices

Answer 7

What are these chioces?

Answer 20

The first derivative of this function is?
Can you get it?

Answer 21

its 3

Answer 22

2x is what i got

Answer 23

Great!

Answer 24

So if we substitute with the given point in this derivative (slope), what you got?

Answer 25

Do you follow?

Answer 26

no im lost im sorry

Answer 27

What is the slope?

Answer 28

\[slope=\frac{ dy }{ dx }=2x\]
Good?

Answer 29

Substitute with (3,12) in the slope
i.e replace every x with 3
You will get:2(3)=6

Hope that helps
