We are told that f(x) = x + 2. We want to find 
.
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
It has turned about 150 degrees going from 2-9 counter clockwise on a clock.
The second answer is correct. On the paper, CD are in the same spots as XY, and so forth for the other segments.
The slope of the graph is -1/2 using the rise over run method it rises up one and too the left twice so it would he -1/2
Answer:
C =47.1 inches
Step-by-step explanation:
The circumference is given by
C = pi*d
C = 3.14 * 15
C =47.1 inches
