This week, I learnt how to solve a function notation equation. Function notation equations look complicated when first viewed, but aren’t as complex as they seem.

Here is our practice equation:

If f(1) = p, what is f(p)?

First, you need to figure out what the y value is when the x value is equal to 1. On the graph, it is clearly -6.

Now you know f(1) = -6, which also means p=-6.

But now you want to figure out f(p) (or f(6)), which can be done by finding the value of y when the x value is equal to -6. On the graph, it is clearly -1.

Therefore, our final answer is f(p)=-1
