1. y axis can repeat/x cannot repeat
2. Parabola symmetrically across y-axis
Answer:
18
Step-by-step explanation:
25 + 47 = 72
72 ÷ 4 = 18
The function rule for x is +1. When you want to get the next number in the set, you add one to the previous number. For example, -1 + 1 = 0.
The function rule for y is - 5. When you want to get the next number in the set, you subtract five to the previous number. For example, 9 - 5 = 4.
Hope this helps!
