Answer:f(-2)=2
Step-by-step explanation:
-x^2-5x-4
= -(-2)^2-5(-2)-4
= -4+10-4
= 2
The number is 6 because 14+6=20 and 6 is less than 14. Hope this helps.
Answer:
D is the true statement
Step-by-step explanation:
A
h(4)=13 and h(20)=13, so h(4)=h(20) and it is not true that h(4)<h(20)
B
This is untrue as we can see that the graph reaches its peak at h(12), so it would be symmetric about the line t=12, not t=10.
C
This is untrue as for all values of t less than 24, the height above the ground, h(t), is greater than zero.
D
This is true because as we can see from the table, when t values are equal distances from 12 (eg. 8 and 16), their h(t) values are the same.
2
12= 2 * 6
26= 2 * 13, gcf is 2
