Make graph for bth equatin: f(x)= -3(x+2)^2(x-1) f(x)= -2x(2x+7)(x+2)(x-1) Pls help w this ques use detailed explination thanks

Use calculus to sketch the graph of the function given by f(x) = ³ – x² – 6x+4. Show all steps clearly.

Given the function f and g below, find g(f(1)). F(x)=x+1 G(x)= -2x^2-3x+5

Given the two functions below​ (whose terms are not necessarily written in descending​ order), find ​(f-g)(x) f(x)=2x^4+5x^6-9+6x^5 and g(x)=-7+8x^5+9x^6-7x^4
