Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function. f(x) = -2x4 + 4x3 + 3x2 + 18

Nookie1986 [14]

$f(x) = -2x^4 + 4x^3 + 3x^2 + 18$

$18:\{\pm1;\ \pm2;\ \pm3;\ \pm6;\ \pm9;\ \pm18\}\\2:\{\pm1;\ \pm2\}\\\\Answer:\boxed{\{\pm\frac{1}{2};\ \pm1;\ \pm\frac{3}{2};\ \pm2;\ \pm3;\ \pm\frac{9}{2};\ \pm6;\ \pm9;\ \pm18\}}$

Answer:

common ratio is 4

Step-by-step explanation:

3, 12, 48, 192, 768, . . .

LEts find the common difference

$12-3= 9$

$48-12= 36$

There is no common difference

LEts find out common ratio by dividing the second term by first term

$\frac{12}{3} =4$

$\frac{48}{12} =4$

$\frac{192}{48} =4$

So common ratio is 4
