Question

If P(x) = 4 x cube - 12 x square + 14 x - 3 find P (1/2)​

Answer 1

Answer:

Step-by-step explanation:

4×(1/2)^3 -12×(1/2)^2+14(1/2)-3

= 4×(1/8)-12×(1/4)+7-3

=(1/2)-3+5)

=(1-6+10)

=5

Answer 2

Answer:

$P(\frac{1}{2})=\frac{3}{2}$

Step-by-step explanation:

Given : $P(x)=4x^3-12x^2+14x-3$

We have to find the value of $P(\frac{1}{2} )$ that is we have t find the value of Given polynomial P(x) at $x=\frac{1}{2}$

Consider the given polynomial $P(x)=4x^3-12x^2+14x-3$

Put  $x=\frac{1}{2}$

$P(\frac{1}{2})=4(\frac{1}{2})^3-12(\frac{1}{2})^2+14(\frac{1}{2})-3$

Simplify, we have,

$P(\frac{1}{2})=\frac{1}{2}-3+7-3$

$P(\frac{1}{2})=\frac{3}{2}$

Thus, $P(\frac{1}{2})=\frac{3}{2}$
