Answer 3

how far did you get with this?

Answer 4

Well Im not sure how to start to be honest Are there steps I can take to get what I need?

Answer 5

y = f(x)

So y = f(4.5) means find the y value when x = 4.5

place a vertical line at x = 4.5 on the x axis

where does this vertical line cross the function?

Answer 6

Well i dont think it crosses 5 if its f(4.5)=5 but why would you find the value of x if y means f(x)
