Using set-builder notation it is written: It is important to get the Domain right, or we will get bad results! Now f(x)=3/(x-2) which is equal to f(g(x))=3/[(2/x)-2]. The final answer is 3x/(2-2x), x cannot equal to: 0,1, nor 2. , For these uses, see Variable (mathematics) and Constant (mathematics). Why is my calculator giving me a huge number for sin(3.140625)? What would you do to F(x) to create G(x)? . N sketch the graph of g(x)" I dont understand what is asking me to do.

(gof)(x) what does this mean ?-----It is called the "composite" of f and g.-----Here is an example: Assume f(x) = 2x+1---Assume g(x) = 3x-5 ◻ the letter which you use to label a function has no special meaning. τ B The advantage of … ⟨ Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. What does generation x mean? Thanks for your vote!
