Prove that when x>1, a triangle with the side length a=x^2-1, b=2x, and c=x^2+1 is a right triangle. Use the Pythagorean theorem and the given side links to create an equation use the equation to show what does triangle shows the rule describing right triangles. Explain your steps.

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?
