X/2 - 3 + 4x^2 + x - 4

=4x^2 +  3/2 x − 7

Step-by-step explanation:

Let's simplify step-by-step.

x /2  −3 + 4x^2 + x − 4  

=  1 /2 x + −3 + 4x^2 + x + −4

Combine Like Terms:

=  1 /2 x + −3 + 4x^2 +x + −4

= (4x^2) + (  1 /2 x + x) + ( −3+−4 )

= 4x^2 + 3 /2 x + −7

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

i think is g(1)=-1.

hope that i can
