Question

Which of the following statements have the same result? Explain each step in solving each one.

I. f(3) when f(x) = 2x + 2
II. f−1(4) when f(x) =3x minus 4, all over 5
III. y + 10 = 2y + 1

Answer 1

Please help,it is very much needed at the moment.

Answer 2

Anyone out there.........?I have been waiting for quite some time.

Answer 3

for I: f(3) means plug in x = 3 into the function. what does 2x + 2 equal when x = 3?

II: it's asking for the value of the inverse function at x = 4. so you'll need to calculate the inverse of f(x).

f(x) =(3x - 4)/5
swap the f(x) and the x to get

x = (f(x) - 4)/5

and solve this to get f(x). once you do that, plug x = 4 into f(x).

III: y + 10 = 2y + 1
solve this equation. you can subtract y from both sides, then subtract 1 from both sides, to solve for y.

once you have all three values calculated, see which ones have the same answer.

Answer 4

correcting a small typo:

f(x) =(3x - 4)/5
swap the f(x) and the x to get

x = (3f(x) - 4)/5

needs to be a 3 in front of the f(x)

Answer 5

Vocaloid ,I want to say thank you for your time on helping me on my question.Overall, I am very appreciative of you help.Is that as well all the help and or steps for each
function,to be exact?

Answer 6

yes, these are the steps for the calculations for each function. is anything unclear?

Answer 7

No,just making sure.Have a good rest of your day,Vocaloid.By the way,I am a big fan of your profile picture.
