Find the equation of the tangent line to y=ln(x) at x=1. (b) Use the tangent line to calculate approximate values for ln(1.4) and ln(2.4). NOTE: Round your answers to one decimal place.
a) y = x-1, ln(1.4) ≈ 0.4, ln(2.4) ≈ 1.4
b) y = x, ln(1.4) ≈ 0.3, ln(2.4) ≈ 1.2
c) y = x-1, ln(1.4) ≈ 0.4, ln(2.4) ≈ 1.2
d) y = x, ln(1.4) ≈ 0.3, ln(2.4) ≈ 1.4
