Answer 3

can't help you answer questions while you're doing a test/exam. Read the code of conduct.

Answer 4

its formative, meaning it doesnt count as a grade.

Answer 5

can you just help?

Answer 6

In the inverse of an equation you flip the roles of the "x" and the "y" variables
so if f(x) = 7x + 12 (which is y = 7x+12)
then the inverse would be x= 7y+12
then you isolate "y" and divide by 7 to find the value of y

Answer 7

Also, an important thing to note is that when solving for the inverse of f(x),
I would treat it its inverse as "y" instead of f(x) because until you solve completely, you can't know if it's a function or not (which f(x) denotes)

thanks, i actually get it now! @slottedpig
