an equation for the line tangent to the graph of the differentiable function f at x=3 is y=4x+6. which of the following statements must be true?

C. II and III

Step-by-step explanation:

See attachment for complete question

Given

 differentiable at

Start by representing y as ;

Solving (I):

Substitute 0 for x in

I is not true

Solving (II):

Substitute 3 for x in

II is true

Solving (III):

First , we have to differentiate  

Then, substitute 3 for x in

III is true

idk

step-by-step explanation:

i don't know

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
