Tracing ln[1+3x] and 4ln + 3ln[-1+x]

How can I trace Ln[1+3x] and 4ln + 3ln[-1+x]in the same graph? The question is Section 11.11 – (Not in the book) Find the Taylor Polynomial 𝑇10 "() for the function 𝑓 (π‘₯) centered on the number π‘Ž. Plot 𝑓 π‘₯ and 𝑇10 π‘₯ on the same plane xy between -5 ≀ π‘₯ ≀ 5. Use the Taylor polynomial to find the value of y when x = 2 and compare it to the value of y real for 𝑓 π‘₯ οΏΌ when x = 2.
𝑓 οΏΌ π‘₯ οΏΌ = ln οΏΌ 1 + 3π‘₯ οΏΌ centered on π‘Ž = 1. I have the T10 but I can not graph it.
