Question

I will medal and fan, PLS HELP

Which of the following expressions is the inverse of the function y = 3x + 4?

y = 3x − 4

y = –3x − 4

y equals quantity x minus 4 divided by 3

y equals quantity x plus 4 divided by 3

Answer 1

Answer 2

so to find the inverse you have to switch x and y and then get y alone again

Answer 3

I got C, I JUST WANTED TO CLARIFY @RhondaSommer

Answer 4

so \[y=3x+4\]changes to\[x=3y+4\]thensubtract3y from both sides and you get \[-3y+x=4\]then subtract x from both sides and you get\[-3y=-x+4\]and then divide -3 on both sides to get y alone and you get\[y=\frac{x}{3}-\frac{4}{3}\]

Answer 5

so you are correct :)
