Question

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

Answer 1

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

Answer 2

(F o G)
who is "o"?

Answer 3

f(g(1))

Answer 4

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

Answer 5

I think you posted f(x) incorrectly @jfry

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

Thank you

Answer 11

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

Answer 12

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

Answer 13

Im not sure im getting this

Answer 14

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

Answer 15

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

Answer 16

Sometimes it helps to make a diagram of the function f prepared to receive the function g
