A) y = e^(-x) @ x = -1

dy/dx = (-1)(1)(e^(-x))

= -e^(-x)

f'(-1) = -0.368

f(-1) = 0.368

y =mx+b

0.368 = (-0.38)(-1) + b

0=b

y=-0.368x

B) y = 2 - e^(-x) @ x=1

dy/dx = 0 +(-1)(-e^(-x))

= e^(-x)

f'(1) = -0.368

f(1) = 1.632

y=mx+b

1.632 = (-0.38)(1)+b

2 = b

y= -0.368x + 2

Is this correct? I feel funny about it.
