f[g(x)] = 7x + 15 f[g(x)] = 7x + 27 f[g(x)] = 7x2 + 15 f[g(x)] = 7x2 + 27
you replace the x in f(x) by g(x)
So the answer would be C?
the 7 multiplies the whole of x + 2 not just the x
alright to be honest I still dont quite understand, and I dont want you to just give me the answer but im confused
instead of x we have x +2 so its 7(x + 2) + 13 the x+2 must be put into parentheses
now distribute the 7 over the x = 2 in the parentheses
* x + 2
ohh alright that makes it easier, seeing the actual equation written out helped
now add 13 and 14 and you have it
alright so the answer is B. Thank you so much for your help :). Ill give you a medal
yes B is correct
Thank you so much for your help!
