Question

The three solutions of the equation f(x) = 0 are 4, 8, and 11. Therefore, the three solutions of the equation f(2x) = 0 are...

Answer 1

f(x) = (x - 4)(x - 8)(x - 11)

f(2x) = (2x - 4)(2x - 8)(2x - 11)

= (2)(x - 2)(2)(x - 4)(2)(x - 5.5)

= 8(x - 2)(x - 4)(x - 5.5)

The solutions of f(2x) = 0 are 2, 4, and 5.5.
