Question

How to Define the following functions?

help please..

3. f(x)=x^2+1; g(x)=3x-2

a. f+g
b. f-g
c. f⋅g
d. f/g
e. g/f

Answer 1

Part A: Add x^2 + 1 and 3x - 2 together and simplify.
Part B: Subtract 3x - 2 from x^2 + 1 and simplify
Part C: Multiply ..........
You get the procedure now probably

Answer 2

You won't be able to simplify d and e so don't stress too much on those.

Answer 3

already have answer in A & B but for C,D,& E still dont have

Answer 4

Part C : fg(x) = (x^ + 1)(3x - 2) = now just FOIL that out.

Answer 5

please help how to solve C,D, & E

Answer 6

C. f.g= (x^2+1).(3x-2)
i use FOIL to get this
(x*3x)+(x*-2)+(1*3x)+(1*-2)
3x^2+(-2x)+3x+(-2)
f.g= 3x^2+x-2
