Question

For the function p defined by p(m)=2m2−4m+3, find p(13).

Answer 1

Answer:

Option C

Step-by-step explanation:

=> p(m) = $2m^2-4m+3$

Putting m = $\frac{1}{3}$

=> p(1/3) = $2(\frac{1}{3})^2-4(\frac{1}{3} )+3$

=> p(1/3) = $\frac{2}{9}-\frac{4}{3} +3$

=> p(1/3) = $\frac{2-12+27}{9}$

=> p(1/3) = $\frac{17}{9}$

Answer 2

Answer:

$\frac{17}{9}$

Step-by-step explanation:

$2\left(\frac{1}{3}\right)^2-4\left(\frac{1}{3}\right)+3$

$2\left(\frac{1}{9}\right)-4\left(\frac{1}{3}\right)+3$

$\frac{2}{9}-\frac{4}{3}+3$

$\frac{2}{9}-\frac{4}{3}+\frac{3}{1}$

$\frac{2}{9}-\frac{4 \times 3}{3 \times 3}+\frac{3 \times 9}{1 \times 9}$

$\frac{2}{9}-\frac{12}{9}+\frac{27}{9}$

$\frac{2-12+27}{9}$

$=\frac{17}{9}$
