Question: Use synthetic division to verify the upper and lower bounds of the real zeros of f. 1. f (x) = 4x3 3x2 + 4x

Use synthetic division to verify the upper and lower bounds of the real zeros of f.
1. f (x) = 4x3 − 3x2 + 4x - 3
(a) Upper: x = 1
(b) Lower: x = −1/4
2. f (x) = 2x3 − 5x2 − 14x + 8
(a) Upper: x = 8
(b) Lower: x = −4
