Can anyone please help me solve these? Please, please, please For questions 1 - 5, use the following functions:

f(x) = 3x - 7
g(x) = x² + 3x-4

1. Find (f+9)(x).
2. Find (f-9)(x).
3. Find (f. g)(x).
4. Find (f/g)(x)
5. Find (g/f)(x)

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
