The given two-parameter family is a solution of the indicated differential equation on the interval (−∞, ∞). determine whether a member of the family can be found that satisfies the boundary conditions. y = c1x2 + c2x4 + 3; x2y'' − 5xy' + 8y = 24 (a) y(−1) = 0, y(1) = 8 a member can be found. a member cannot be found. (b) y(0) = 8, y(1) = 5 a member can be found. a member cannot be found. (c) y(0) = 3, y(1) = 0 a member can be found. a member cannot be found. (d) y(1) = 3, y(2) = 15 a member can be found. a member cannot be found.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false.
