Answer:
Point C′ of the image coincides with point E of the preimage.
Point D′ of the image coincides with point F of the preimage.
Step-by-step explanation:
A translation counterclockwise 60° moves point A to F, F to E, E to D, et cetera. A translation counterclockwise 180° moves any vertex to the opposite vertex, so A moves to D, B to E, C to F and vice versa. Then, a translation counterclockwise 240° is a combination of the two aforementioned translations and moves A to C, F to B, E to A, D to F, C to E and B to D, creating the hexagon A′B′C′D′E′F′ (see figure attached).

Step-by-step explanation:
Function composition and transformation combines functions together using operations such as addition, subtraction, multiplication, division and substitution. To find each, perform the operation with the functions f(x) = 2x+1 and .
(f+g)(x) is the functions f and g added together with 2 substituted for x.
(f·g)(x) is function composition that means f(g(x)) or substitute g(x) into f(x).
f(x) / g(x) is division of the two functions. Division can only occur with polynomials if they share the same factors or things which multiply to create them. If none are present, do not simplify.
This cannot be simplified.
f(2) + g(-2) means find the function value of f at 2 and the function value of g at -2 then add them together.
