The comments are that they both are multidigits numbers
The pythagorean theorem says that a² + b² = c²
You're given the b and the c so substitute the values in: a² + 12² = 15²
a² + 144 = 225; subtract 144 from both sides
a² = 81; square root each side
a = 9, or choice C
-4^-4 is the answer to your question
According to Google, yes.... any details, I have no idea, but I hope I helped in any way, haha
Good luck~~
The parent function for quadratic equations is as followed:

where a and b represent vertical and horizontal stretches, respectively, h is the horizontal shift, and k is the vertical shift.
So going from

to

,
We are shifting 1 to the left and 6 up.
The horizontal shift is in the negative direction because in the equation, h=-1 because:
The answer is A.
