Write the function graphed below in the form f(x)=a/x-h +k

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.

answer: 8

step-by-step explanation:

11) obtuse

13)right

15) acute
