All right. We have the function. Special function of affects is equal to and to the eggs. Okay, on we have the point from the ER graph and 38 So we have f off melody of three to be equal Thio Hey to the native three instead of actually replace it with native three. It is equal to y which is eight. And this Give us the implication that, uh, one over eight to the third it's equal to eight. He cross multiply and this gives us Ah won over eight is equal to a the third and we can take the cubic would of both sides. And so this gives us keeping mood off. One over eggs is equal. Do a good off. Whatever. Eight iss one over Cuba Good of eight, which is to so 1/2 is equal to hey And that tells us that our function if X is equal to 1/2 which is a to the ex that so

The number 2 is also the smallest & first prime number (since every other even number is divisible by two).

If you write pi (to the first two decimal places of 3.14) backwards, in big, block letters it actually reads "PIE".
