J.
Step-by-step explanation:
The graph on option F showing (3,4) and (5,10). This is wrong because 5 should result in 14 (5, 14).
If you put x=-4 on option G, it will be:
f(x)= x^2 +3x +4
f(x)= -4^2 + 3(-4) +4
f(x)= 16-12+4
f(x)=8
It is wrong because -4 should result in 32 (-4, 32).
Option H also wrong cause they have x and f(x) switched around. It should be x=-4 and f(x) =32, but they show x=32 and f(x)= -4 instead.
Option J true because it shows the same result as the quadratic function h (-4, 32), (3, 4), (5, 14), and (7, 32).

Step-by-step explanation:
The graph of the quadratic function h passes through the points (-4, 32), (3, 4), (5, 14), and (7, 32).
In terms of arrow diagram:
(-4,32) has the mapping![-4\to 32](/tpl/images/0357/3412/5304f.png)
(3,4) has the mapping![3\to 4](/tpl/images/0357/3412/5e4dc.png)
(5,14) has the mapping![5\to 14](/tpl/images/0357/3412/b5ccc.png)
(7,32) has the mapping![7\to 32](/tpl/images/0357/3412/ad6a3.png)
Therefore mapping diagram shows the same relationship as h.
Ответ:
20 degrees
Step-by-step explanation:
since JIH is equal to 25x+5 degrees, then JIZ and ZIH together equal that. but, since it's a straight line, JIH equals 180, so you can set 25x+5 equal to 180. therefore, x equals 7. then you can plug in 7 for x for JIZ and you get 2(7)+6 or 20.
