Q1) Solve the equation fg(x) = 27. Firstly, we must find the composite function fg(x) in terms of x before we solve it. In order to do this, we can break down the function in the following way: …

(f+g)(x) is shorthand notation for f(x)+g(x). So (f+g)(x) means that you add the functions f and g (f-g)(x) simply means f(x)-g(x). So in this case, you subtract the functions. (f*g)(x)=f(x)*g(x). So …

You can put this solution on YOUR website! I think one is a composition where you substitute for . The other is an actual multiplication of two functions.

Let f(x) = 2x + 1 and g(x) = x^2 - 4 (fg)(x) has two meanings whether it is component wise multiplication or composition if it is multiplication then (fg)(x) = f(x)*g(x) and if it is composition …

Next I would explain the range of fg is dependant of the funtions themselves. An expression would need to be derived for fg, and hence using the known domain of g, the range of fg could be …

c) Solve fg(x) = gf(x). Hint: Calculate f(g(x)) first. Then think. -----Comment from student: Thanks i have solved the two questions! im still stuck on the last one though, i have found fg(x) and …

You can put this solution on YOUR website! f+g(x) means add the functions: 9-6x+x+7=-5x+16 (f + g)(x) = [-5x+16]

Algebra -> Rational-functions-> SOLUTION: If f(x)= 4x-5 & g(x)=3x find (fg) (x) Log On Algebra: Rational Functions, analyzing and graphing Section Solvers Solvers

Question 421490: The question says: Find x and the measure of each side of the triangle. This is the problem: Triangle FGH is equilateral with FG= x+5, GH= 3x-9, and FH= 2x-2. I don't …

You can put this solution on YOUR website! The set-up is: For each pair of functions, find (f+g)(x), (f-g)(x), and (fg)(x)...Then evauluate each function at 2.
