Which of the following equations is of a parabola with a vertex at (3, 0)? y = (x - 3) 2
y = (x + 3) 2
y = x 2 - 3
y = x 2 + 3

The answer is y = (x - 3)^2.

I hope this helps! Please give brainliest.

i’m sorry but i don’t know sorry

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
