The function f(x) = –1∕3x2 is shifted down one unit. Which of the following function equations represents this translation? A)

f(x) = –1∕3x2 + 1

B)

f(x) = –1∕3(x – 1)2

C)

f(x) = –1∕3(x + 1)2

D)

f(x) = –1∕3x2 – 1

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
