Serena wants to wrap ribbon around the edge of the picture frame represented in the drawing. Which is the simplified form of the expression representing the length of ribbon Serena will need? A. 9x – 13.2 B. 4.5x – 6.6 C. 9x – 14.8 D. 2(3.5x – 7) + 2(x + 0.4)

A.9x – 13.2

Step-by-step explanation:

2*(3.5x-7+x+0.4)=2*(4.5x-6.6)=9x-13.2

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
