f(x)=-3(x-2)^2-1 and g(x)=2x-3/x+5 A. f(g(2)) B. G(f(2))

Question

f(x)=-3(x-2)^2-1 and g(x)=2x-3/x+5      A. f(g(2))      B. G(f(2))

zale101 · Answer

$$f(\frac{ 2x-3 }{ x+5 })$$
it says f(g(2)) this means for the equation of g, the x values for it is 2

plug in 2 before you compose with the function of f.

zale101 · Answer

after your done substituting that, you'll have f(and some number)

did i make it clear?

anonymous · Answer

the thing that is throwing me of is the f(g(2)) thing

zale101 · Answer

yeah, f(g(2)) is f of g of 2
g of 2 means that you plug in 2 in the function of g
$$f(\frac{ 2(2)-3 }{ 2+5 })$$

zale101 · Answer

we are not composing f to g yet, we are composing g and 2 right now

anonymous · Answer

so do the second question or part of the question(b) then go back to A

zale101 · Answer

we are still solving for A, don't worry about the other problems, we are not there yet
