Question
. Using any of the methods covered in the book, find the real zeros of the function,
f(x) = 2x* + x' - 7x² - 3x + 3
%3D
Using the Zero function of the calculator (and being sure to change the Window settings as
needed), find the real zeros of the function, f(x) = -75x* – 35x² + 20x + 15 (round to three decimal
places)
Find the real solutions of the polynomial equation: x* + 2x² = 15
Solve the polynomial inequality and give the answer in interval notation:
(x – 3) > 2
