g(7) = 2(7) + 2 = 16
cwrw238
  • cwrw238
oops - my bad thinking now you need to plug x = 16 into f(x)
cwrw238
  • cwrw238
4(16) + 21 = ?

- this gives you the value of f[g(7)]

Given the functions f(x) = 7x + 13 and g(x) = x + 2, which of the following functions represents f[g(x)] correctly? f[g(x)] = 7x + 15 f[g(x)] = 7x + 27 f[g(x)] = 7x2 + 15 f[g(x)] = 7x2 + 27
cwrw238
  • cwrw238
you need to replace the x in f(x) - that is 7x + 13 - by g(x) which is x + 2 then simplify so we get 7(x + 2) + 13 - can you simplify this further?

  • anonymous
yes but how ?
cwrw238
  • cwrw238
7(x + 2) + 13 = 7*x + 7*2 + 13 = ?
cwrw238
  • cwrw238
you distribute the 7 over the x + 2
cwrw238
  • cwrw238
- that was the first step
cwrw238
  • cwrw238
so now its just simplifying 7x + 7*2 + 13

is it A ?
cwrw238
  • cwrw238
no what is 7*2 ?
cwrw238
  • cwrw238
7 times 2
cwrw238
  • cwrw238
surely you know what 7 times 2 is?
cwrw238
  • cwrw238
right so we have 7x + 14 + 13 - now is just one add and you have the answer
cwrw238
  • cwrw238
add the 2 numbers
cwrw238
  • cwrw238
correct 7x + 27
