Hello!

Recall that the transformations form of a parabola is:
f(x) = ±a(b(x-h)) + k where:
a = vertical stretch/compression
b = horizontal stretch/compression
h = horizontal shift, x-coordinate of vertex
k = vertical shift, y-coordinate of vertex
In this instance, the parent function is f(x) = 3x^2. There is a vertical stretch of 3.
However, there is a point (7, -2) that needs to be included. Substitute these values into the transformation formula:
h = 7
k = -2
f(x) = 3(x - 7)² - 2 is the equation with (7, -2) as the vertex.
0-9 = 10 numbers
1st digit can be 1 0f 10
2nd digit can be 1 of 9
3rd digit can be 1 of 8
4th digit can be 1 of 7
10 * 9 *8*7 = 5040 different combinations
Three unit's would be the numbers:
1, 2 and 3.
Any number you choose must be greater than 3 for example:
5, 8 or 10
Hope it helped,

7/8= 7 divided by 8 = 0.87
0.87 divided by 2 = 0.43
0.43= 43/100 OR you can say 3/7 as well but it's 0.42,but when rounded it 0.43..
1. being destroyed would be a negative number
2. water increasing in temperature is a positive number
3.descending would be a negative number
4. credit card charge would be a positive number
