Question

for f(x)=3x+1 and g(x)=x^2-6, find (f o g)(4)

Answer 1

31

Answer 2

determine the value of g(x) when x=4; then apply that value from g into f(x)

Answer 3

(f o g) simply means f[g(x)] where g(x) is the value of f's stuff

Answer 4

they prolly should use different variables in them to lessen any confusions perhaps

Answer 5

they should and I never understand (f o g), they should've just said:
f(g(x))

Answer 6

i blame leibnez :)

Answer 7

would you all agree with the answer of 31 from jkip

Answer 8

lets see:

(4)^2 - 6 = ?

Answer 9

10...?

Answer 10

10 is correct :)

3(10) + 1 = ?

Answer 11

g(4)=4^2-6=10
then F(10)=3*10+1=31

Answer 12

thankyou both
