Find the expression that represents the length of the hypotenuse of a right triangle whose legs measure m^2-n^2 and 2mn

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6
