Question

ok can't figure this one out. How do i get the b value??

Answer 1

By "b," do you mean the slope of the tangent line?

Answer 2

yes here's the answerL(x)=10x-13 and i got all those values except the 13 (which is the b value, y=mx+b)

Answer 3

I was looking at these instructions. Let's follow them.

Answer 4

Did you get y' = 3x² -2 for the first derivative equation?

Answer 5

I agree that the slope of L(x) = 10.

Answer 6

Did you get (2, 7) at the point of tangency?

Answer 7

y - 7 = 10( x - 2)

and then ... ? @Math2400

Answer 8

ohhh i thout i was trying to use y=mx+b to solve for b cuz that's what someone suggested when i asked the same question earlier. Thank you sooo much!!

Answer 9

You are welcome.
