In grade 11, i am learning about transformation functions. how do i find an equation by looking at a graph?

You have to remember what each formula looks like when it is graphed

You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero. This is another way to find the y-intercept, if you know the equation, the y-intercept is the solution to the equation when x = 0.

(1/x + 1)^2 + 6 (1/x + 1) +5
