Answer:

1. y = 9280 - 20x

2. f(y) = 6.37y - 3

Step-by-step explanation:

1. The equation is given to be $\frac{1}{16}x + \frac{1}{320}y - 29 = 0$

Now, rearranging the function we can write

$\frac{y}{320} = 29 - \frac{x}{16}$

⇒ y = 9280 - 20x

Hence, this is the equation as a function of x. (Answer)

2. The given function is y - 6.37x = - 3

Therefore, we can write, y = 6.37x - 3

Hence, f(x) = 6.37x - 3

⇒ f(y) = 6.37y - 3.

Hence, option D is true. (Answer)
