Question

Can someone please check my answer

Answer 1

Which one you choose? lol

Answer 2

My answer is 2.5

Answer 3

Nope

Answer 4

the question is what is the slope at x = 0.

both lines meet up at this point.

since sam won't answer i won't either. guess again :)

Answer 5

Wanna try again? farmergirl?

Answer 6

then it is 1

Answer 7

is that right

Answer 8

nope

Answer 9

is it 0

Answer 10

is that right

Answer 11

nope

Answer 12

then does it not exist

Answer 13

I dont understnad what I am doing wrong

Answer 14

Sam can you help me

Answer 15

You know that if you can find the equation, then differentiate it you'll get the answer

Answer 16

Take (1,4) and (0,1)
m=3
Then use point slope formula
y-1=3(x-0)
y=3x+1
differentiate it you'll get
y=3
Which means
f'(x)=3

Answer 17

oh ok I am following or some reason when I said 2.5 I meant to type 3 oh my goodness. Ok so just double checking 3 is the answer?

Answer 18

There are 2 sides, so you'll have to do this again for the other side, the gradient is, -1/2
Equation will be
y=-1/2x +1
differentiate it you'll get -1/2

Answer 19

So its 3 and -1/2

Answer 20

ok thanks
