Question

if p(x)=x^3-4x+3 find the value of p(2)+p(1/2)
​

Answer 1

Answer:

p(x)=x^3-4x+3 find the value of p(2)+p(1/2)

$p(2) = 2 {}^{3} - 4(2) + 3 \\ \: \: \: \: \: \: \: \: \: = 8 - 8 + 3 \\ \: \: \: \: \: \: \: \: \: = 3$

$p( \frac{1}{2} ) = ( \frac{1}{2} )^{3} - 4( \frac{1}{2}) + 3 \\ \: \: \: \: \: \: \: \: \: \: = \frac{9}{8}$

$3 + \frac{9}{8} = \frac{33}{8}$
