Solve the polynomial inequality and graph the solution set on a
real number line. Express the solution set in interval
notation.
(x-6)(x+3)>0
Use the inequality in the form f(x)>0, to write the intervals
determined by the boundary points as they appear from left to right
on a number line.

(Simplify yours answers. Type your answer in interval notation.
Type exact answers, using radicals as needed. Use integers or
fractions for any numbers in the expressions.)
Using Matlab, consider the function f(x) =
x^3 – 2x + 4 on the interval [-2, 2] with h
= 0.25. Write the MATLAB function file to find the
first derivatives in the entire interval by all three methods i.e.,
forward, backward, and centered finite difference
approximations.
Could you please add the copiable Matlab code and the associated
screenshots? Thank you!
