Part A: 14 + 14 = y or 14•2 = y
Part B: (n•2) - 2 = a
Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.
3,062.85 is de answer having on two decimals
If you are describing transformations with respect to the graph of f(x) = x:
f(x) = x has no transformation
g(x) = (x+2) - 3 is the graph of f(x) translated 2 units left and 3 units down
2(h(x) = x-1) is the graph of f(x) vertically expanded by a factor of 2 and then translated 1 unit right
d(x) = 1/2x + 2 is the graph of f(x) vertically compressed by a factor of 1/2 and then translated 2 units up
A because 16x9=144 and 4x6=24 and 144-24=120
