You could actually find the compositions and thus have something to compare. You haven't shared the list of possible answer choices.
(f+g)(x) = 5x - 3 + x + 4 = 6x + 1
(f-g)(x) = 5x - 3 - x - 4 = 4x - 7
(f*g)(x) = (5x-3)((x+4) = 5x^2 + 20x - 3x - 12 = 5x^2 + 17x - 12
There are also the quotient (f/g)(x) and the compositions f(g(x)) and g(f(x)).
WRite them out.
Then you could arbitrarily select x values, such as 2, 10, etc., subst. them into each composition and determine which output is greatest.
Answer:
sod- 1662.6
fencing- 807.6
all- 2470.2
Step-by-step explanation:
sod-
25.5 * 8.25 = 207.825
207.825*8= 1662.6
fencing-
8.25+8.25+25.5+25.5= 67.3
67.3*12= 807.6
fencing + sod
1662.6 + 807.6= 2470.2
