<span>In the laws of mathematics, especially in rounding off
digits, you should take note of the digit following that number no matter how
long or short a number is. If the number is preceded by numbers between 0-4,
the number does not change. However if its is preceded by numbers between 5-9,
add one to the number. In this problem, you are required to round off each
number to the nearest ten million before adding them. So 22,471,000 becomes
20,000,000 and 36,730,000 becomes 40,000,000. Add the both of them and you will
get 60,000,000. The answer is letter A.</span>

Answer:
1. 1458
2. 500 or -500
Step-by-step explanation:
1. a4=54, a5=162
r = 162/54 = 3
a7 = a5 × r²
= 162 × 3² = 1458
2.a4=-4, a6=-100
r² = -100/-4 = 25
r = +/- 5
a7 = a6 × r
= -100 × +/- 5
= +/- 500
F(x) = a(x - h)³ + k
The parent graph is F(x) = x³
k - shifts the parent graph up k-units (or down if it is negative). This is also called a vertical shift.
h - shifts the parent graph to the right h-units (or left if it is negative). This is also called a horizontal shift.
a - stretches the parent graph vertically by a factor of "a"
Additonally, the coordinate (h, k) is the center/vertex of the graph.
