You make a purchase at a local furniture store that is too large to take home yourself. For a small fee, the store will deliver your purchase. For your purchase, you pay for the item, the tax and the delivery fee. Taxes are at 14% and the delivery fee is $20. If x represents the price of the item, write a function that represents the amount to be paid before taxes, including delivery fee: O a) f(x) = x+20 Ob) f (x) = x+1.14 Ocf(x) = 20x O d) f (ac) = 1.14 (x + 20)(f o g) (x) and (go f) () are the same function. This statement is: (a) always true b) false for most functions f(x) and g(x) c) true for most functions f(x) and g(x) O d) always falsesaved The sum of two linear functions is: a) always a horizontal line Ob) always vertical line O c) always linear function. Od) may be a linear or horizontal line.Given the graphs of two functions f (a ) and g (a), where both are defined at x = a, you can find the y-coordinate of (f + g) (a) by adding the corresponding y- coordinates of f (a) and g (a) a) This statement is always true. b) This statement is sometimes true. O c) This statement is never true
