Question

Let f(x) = x2 + 6 and g(x) = . Find (g ° f)(–7).

Answer 1

if g(x) need to find

Answer 2

x+8/x

Answer 3

first subtitute your value g(f(x))
which mean put the function of f(x) inside the g(x) function

Answer 4

do you get it.. for example
f(x)=x+2 g(x)=x^2+3
g(f(x)) =g(x+2)
=(x+2)^2+3________ here subtitute your f(x) inside your g(x)

Answer 5

okay and what do you get

Answer 6

if g(x)=(x+8)/x or x+(8/x)

Answer 7

my answer has some fractions...
-55/7
384/7
295/49
63/55

Answer 8

(x+8)/x=63/55

Answer 9

thank you
