using similar triangles
Let x be the boy's height
=
cross multiply to get 43.2x=1944
then divide by 43.2 both sides
to get x=45
g(x)=1.5^x−4 is the answer.

19.99+ 0.29m = 73.93
Step-by-step explanation:
bc u add 19.99 extra to every m for .29 (.29m)= and the total is 73.93
Your post would be clearer if you'd please put each function on its own line:
f(x) = (x + 4)2 + 4
f(x) = –(x + 4)2 + 4
f(x) = (x – 4)2 – 4
f(x) = –(x – 4)2 – 4
Also, use "^2" to denote "squaring." x2 has no meaning.
f(x) = (x + 4)^2 + 4 has a parabolic graph with vertex (-4,4). It increases steadily once x is greater than -4. Reject this choice.
f(x) = –(x + 4)^2 + 4 has a parab. graph with vertex (-4,4) also. It decreases steadily once x is greaster than -4. This is the answer.
Analyze the other 2 possible answers in the same way, please.
