What are the zeros of the function y = 2x2 β 3x β 20, and why? a. the zeros are x = β 5 2 and x = 4 because in factored form, the function is y = (2x β 5)(x + 4). b. the zeros are x = β 5 2 and x = 4 because in factored form, the function is y = (2x + 5)(x β 4). c. the zeros are x = 5 2 and x = β4 because in factored form, the function is y = (2x β 5)(x + 4). d. the zeros are x = 5 2 and x = β4 because in factored form, the function is y = (2x + 5)(x β 4)?

Prove (a) cosh2(x) β sinh2(x) = 1 and (b) 1 β tanh 2(x) = sech 2(x). solution (a) cosh2(x) β sinh2(x) = ex + eβx 2 2 β 2 = e2x + 2 + eβ2x 4 β = 4 = . (b) we start with the identity proved in part (a): cosh2(x) β sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 β sinh2(x) cosh2(x) = 1 or 1 β tanh 2(x) = .
