A marketing company is designing a new package for a box of cereal. They have determined that the function C(x) = 4.5 x2 models

Vlad1618 [11]

So the function is

$\\ \rm\rightarrowtail y=4.5x^2$

As we know

x²≥0
x≥0

hence domain is

$\\ \rm\rightarrowtail D_f\in R$

Least value of function is at x²=0 i.e 0

Hence range:-

$\\ \rm\rightarrowtail R_f\in [0,\infty)$

(2x²<span> + 3x - 4) + (8 - 3x) + (-5x</span>²<span> + 2)

= </span> 2x² + 3x - 4 + 8 - 3x - 5x² + 2

= -3x² + 6
