The clock models the length from the center of a clock to the tip of the minute hand as being 28 inches. Which of these is the closest to the total area covered by the minute hand when the hand makes one rotation?

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

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
