Question

K(x) =3x^2-1/2x+4, k=(-3)​

Answer 1

Step-by-step explanation:

k(x)= 3x2-1/2x+4

= 3(-3)2-1/2(-3)+4

= 3(9)+3/2+4

= 27+3/2+4

=65/2

Answer 2

61/2 is your answer

Step by step explanation:-

$here \: u \: go \: with \: your \: answer$

$k(x) = 3 {x}^{2} - \frac{1x}{2} + 4$

It is given that the value of x is -3.

Let's substitute the value of x

Therefore

$k( - 3) = 3( { - 3}^{(2)} ) - \frac{1 \times - 3}{2} + 4 \\ = > 27 + \frac{3}{2} + 4$

Let's take the LCM...

And the LCM is 2

Therefore

$= > \frac{54 + 3 + 4}{2} \\ = > \frac{61}{2} \\ hence \: this \: is \: your \: answer$
