i need help for this problem and to understand the next lesson . Thank you

4.Determine the limits. Be careful to ensure you can apply L’Hopital’s rule before you do.Relative difficulty is indicated by the point values.a. limx+1x-2-2(x2-4)(5 pts)b. lim1-cos(2x)x-01-cos(3x)(5 pts)c.lim x Inx-0+(10 pts)d. limx->oo(1+2)*(10 pts)5.Find all equations of the horizontal and vertical asymptotes of the functionf (x ) =x2 – 3x + 22×2 – 3x + 1USE LIMITS as learned in section 3.6 to justify your answer.(10 pts)
