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:
$ 126
Step-by-step explanation:
9 months is 3/4 of one year
2100 * 3/4 * .08 = 126 dollars interest
Answer:
50 + 25 + (8*5) - (7 + 4)
Step-by-step explanation:
50 + 25 + (8*5) - 7 + 4 = 50 + 25 + 40 - 7 + 4
= 115 - 7 + 4
= 108 + 4
= 112
Using the data you have given, it seems he can cut 1 and a half lawns on a third of a tank of gas. Taking this data, and multiplying it by 3, Nathans lawn mower can mow down 4 one-acre lawns, and a lawn that's half an acre. (Your answer is basically 4 lawns)
X^4 y^2/3. Space 3^4=81 the fourth root of 81 is 3
