f(x)=x^3=x^2 g(x)= x^3/2+5
Determine (F o G)(1)

Question

f(x)=x^3=x^2 g(x)= x^3/2+5
Determine (F o G)(1)

anonymous · Answer

f(x)= x^3 + x^2

anonymous · Answer

(F o G)
who is "o"?

anonymous · Answer

f(g(1))

mertsj · Answer

I am confused by f(x)=x^3=x^2   Is that what it is supposed to say?

hero · Answer

I think you posted f(x) incorrectly @jfry

anonymous · Answer

i did, it f(x)= x^3 + x^2

mertsj · Answer

Now who lectured me about exactly what he is doing?????

hero · Answer

I hope you're not referring to me. I didn't lecture you about anything

mertsj · Answer

$$f(g(x))=(x ^{\frac{3}{2}}+5)^{3}+(x ^{\frac{3}{2}}+5)^{2}$$

anonymous · Answer

Thank you

mertsj · Answer

However, if all you want is the f(g(1)), the simplest approach would be to find the g(1) and put that result into f

mertsj · Answer

g(1)=6
f(6)=216+36=252

anonymous · Answer

Im not sure im getting this

mertsj · Answer

The f(g(x)) means replace every x in the function f with the function g

anonymous · Answer

i got it now, i was having trouble with the x^3/2. i thought it would be 1/2, not 1.

mertsj · Answer

Sometimes it helps to make a diagram of the function f prepared to receive the function g|dw:1329525975930:dw|
