Find possible zeroes<br> f(x)=3x^6+4x^3-2x^2+4
larisa [96]

The possible zeros of f(x) = 3x^6 + 4x^3 -2x^2 + 4 are \mathbf{\pm\{1,2,4,\frac 13, \frac 23,\frac{4}{3}}\}

<h3>How to determine the possible zeros?</h3>

The function is given as:

f(x) = 3x^6 + 4x^3 -2x^2 + 4

The leading coefficient of the function is:

p = 3

The constant term is

q = 4

Take the factors of the above terms

p = 1 and 3

q = 1, 2 and 4

The possible zeros are then calculated as:

\mathbf{Zeros = \pm\frac{Factors\ of\ q}{Factors\ of\ p}}

So, we have:

\mathbf{Zeros = \pm\frac{1,2,4}{1,3}}

Expand

\mathbf{Zeros = \pm\frac{1,2,4}{1},\pm\frac{1,2,4}{3}}

Solve

\mathbf{Zeros = \pm\{1,2,4,\frac 13, \frac 23,\frac{4}{3}}\}

Hence, the possible zeros of f(x) = 3x^6 + 4x^3 -2x^2 + 4 are \mathbf{\pm\{1,2,4,\frac 13, \frac 23,\frac{4}{3}}\}

What is the maximum value of P = 4x + 2y, given the constraints on x and y listed below?
Solnce55 [7]
P = 4x + 2y

additional info.
<span>x+2y  <u><</u> 10
y <u><</u> 2
x <u>></u> 0
y <u>></u> 0

y can only be 0, 1, and 2.

x + 2(0) <u><</u> 10 = x <u><</u> 10
x + 2(1) <u><</u> 10 = x + 3 <u><</u> 10 = x <u><</u> 10 - 3 = x <u><</u> 7
x + 2(2) <u><</u> 10 = x + 4 <u><</u> 10 = x < 10 - 4 = x <u><</u> 6

x = 10 ; y = 0 : P = 4(10) + 2(0) = 40 + 0 = 40
x = 7 ; y = 1 : P = 4(7) + 2(1) = 28 + 2 = 30
x = 6 ; y = 2 : P = 4(6) + 2(2) = 24 + 4 = 28

The maximum value of P is 40. Where x is 10 and y is 0.</span>
