the equation of the tangent line is "6x-18"

Answer 1

HI!!

Answer 2

first part is right for sure

Answer 3

so is the second

Answer 4

Hi!
I thought so, but my assignment generator keeps saying that it is wrong! :( Which is why I wanted a second opinion. Thanks bunches!!!

@Nnesha that's what the y will be, 0. but first I had to use lim \[hrightarrow0\][f(a+h)-f(a)]/h

Answer 6

@Nnesha no worries!!

Answer 7

gO_Od luck!!
