Name the possible rational roots for the function using the Rational Root Theorem.
blondinia [14]

Answer:

\pm 1,\pm 3,\pm 5,\pm 15,\pm \frac{1}{3},\pm \frac{5}{3}

Step-by-step explanation:

Given:

The function is given as:

f(x)= 3x^{3}-19x^{2} +23x-15

The possible rational roots for a function f(x) = a_{n}x^{n}-a_{n-1}x^{n-1} +a_{n-2}x^{n-2}+....a_{1}x+a_{0} using the Rational Root Theorem is given as:

\pm (\frac{\textrm{Factors of }a_{0}}{\textrm{Factors of } a_{n}}})

Here, a_{0}=-15,a_{n}=3

Factors of -15 = \pm1,\pm3,\pm5,\pm15

Factors of 3 = \pm1,\pm3

Now, possible roots are given as:

\pm (\frac{\textrm{Factors of }a_{0}}{\textrm{Factors of } a_{n}}})\\\\=\pm(\frac{\pm1,\pm3,\pm5,\pm15}{\pm1,\pm3})\\\\=\pm\frac{1}{1},\pm\frac{1}{3},\pm\frac{3}{1},\pm\frac{3}{3},\pm\frac{5}{1},\pm\frac{5}{3},\pm\frac{15}{1},\pm\frac{15}{3}\\\\=\pm1,\pm\frac{1}{3},\pm3,\pm1,\pm5,\pm\frac{5}{3},\pm15,\pm5\\\\=\pm1,\pm \frac{1}{3},\pm3, \pm 5, \pm \frac{5}{3},\pm15

Therefore, option 1 is correct.
