The quadratic function y=x^2 -8x + 7 can be written equivalently as

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)
