just giving points out everyday because i am doing it this hole 2 weeks so you might get alot of points cuz tomorow i am doing 100

The graph of fx shown below has the same shape as the graph of gx = 3x^2 but is shifted down 2 units

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .

If /is a line of symmetry, plot the partner points for the ones shown. noch 6 5 4 -3 -2 -1
