Consider the parent graph f(x) = x2 . Then, g(x) is a translation according the rule: y = (x + 3)2 + 4. Find the graph g(x).
krok68 [10]
For this case we have the following parent function:
 f (x) = x ^ 2
 We apply the following function transformation:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x + h), move the graph of h units to the left.
 We have then:
 y = (x + 3) ^ 2
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) + k, move the graph of k units up.
 We have then:
 y = (x + 3) ^ 2 + 4
 Answer:
 
The graph g (x) is the graph f (x) 3 units to the left and 4 units up:
 
y = (x + 3) ^ 2 + 4

The circumference of a circular garden is approximately 24 feet. What is the approximate area inside the circular garden? What i
diamong [38]

Answer:

45.86 ft²

Step-by-step explanation:

Circumference of a circle = 2 * pi * r

Circumference = 24

24 = 2 * 3.14 * r

24 = 6.28r

r = 24 / 6.28

r = 3.8216 ft

Approximate area of garden :

Area of circle :

pi * r^2

Area = 3.14 * 3.8216^2

Area = 45.8585273984

Area = 45.86 ft²
