Question

PLEASE HELP: Find f(x) and g(x) so the function can be expressed as y = f(g(x)).
y=7/(x^2+10)

Answer 1

you must look at the formula and see (at least) to steps.
Well, if I look at it, I see a complicated first step: 7/x² and a simple second one: adding 10 to a number.

Answer 2

Go to google, and look up 'Tiger Algebra'. Enter your problem and it can solve it.

Answer 3

it is

Answer 4

\[f(x)=x+10\]

Answer 5

g(x) = x^2 ; f(x) = 7/(x +10)

Answer 6

Now if you have to calculate f(g(x)), this means: put the result of g, which is 7/x² in f. This gives the formula you had: 7/x² + 10.

Answer 7

See? g(x)=7/x² has taken the place of x in function f.
