Question

P(x) = 3x +1 , x=-1/2

Answer 1

Given:

• P(x) = 3x + 1
• x = $\large{\bf{\dfrac{-1}{2}}}$

To find:

• Value of P(x) by putting given value of x.

Solution:

Here, given that p(x) = 3x+1 where x = $\large{\bf{\dfrac{-1}{2}}}$.

Putting value of x in P(x) :

P(x) = 3x + 1

→ P(-1/2) = $\large{\bf{3×\dfrac{-1}{2}+1}}$

→ P(-1/2) = $\large{\bf{\dfrac{-3}{2}+1}}$

→ P(-1/2) = $\large{\bf{\dfrac{-3+2}{2}}}$

→ P(-1/2) = $\large{\bf{\dfrac{-1}{2}}}$

Therefore,

Value of P(x) on the given value of x is -1/2.

Answer:

$\large{\boxed{\bf{\green{P(-1/2)\: =\: -1/2}}}}$
