MATLAB Question:
Evaluate the polynomial expression 3x^3+4x^2+2x?2 at x=4,6,and x=8
x = 4
= 3 x^3+4 x^2+2 x^2
= 3 *4^3 + 4 *4^2 + 2 *4^2
= 3 * 64 + 4 * 16 + 2 * 16
= 192 + 64 + 16
= 272
x = 6
= 3 x^3+4 x^2+2 x^2
= 3 * 6^3 + 4 *6^2 + 2 *6^2
= 3 * 216 + 4 * 36 + 2 * 36
= 648 + 144 + 72
= 864
x = 8
= 3 x^3+4 x^2+2 x^2
= 3 * 8^3 + 4 *8^2 + 2 *8^2
= 3 * 256 + 4 * 64 + 2 * 64
= 768 + 256 + 128
= 1152

multiple choice, Matlab question 3. To solve a set of eqns 2x+3y=5:3x+15y=8, the correct Matlab input is A) [2 3;3 15]/[5; 8] (B) [2 3;3 15]1 [5;8] (C) [2 3:3 15] / [5 8] (D) [2 3:3 15] 1 [5 8]
Prove that the polynomial 9x^4 + 4x^2 − 3x + 7 is irreducible in Q[x].
question starts with P(x) = -2x^3(x-1)(2x^2+1). I was then supposed to express the polynomial in general form and got -4x^6 + 4x^5 - 2x^4 + 2x^3. Then asked to determine the left and right end behavior which I did. What I'm suck on is the final part which is "Find the x-intercepts, if any.". I know im supposed to set y to zero, but I cant figure this one out. I cant find out how to factor it, im stuck....
#2 1. (8 points) Evaluate the limit, without using L'Hôpital's Rule: x² – 2x - 3 lim 2+3 22 – 5x + 6 Note that 3 is a zero of the denominator polynomial, so you need to use the technique of Example 4.2.5(d) p. 113. 2. (8 points) In the previous problem, can L'Hôpital's Rule be applied? If so, evaluate the limit using L'Hôpital's Rule; if not, indicate how the limit expression does not satisfy the conditions required for L'Hôpital's...
