A quadratic function is a function whose highest power for the variable is 2.
h(x) = 3x(x - 2) - 4 = 3x^2 - 6x - 4 is a quadratic function.

Answer:

The correct option is 4.

Step-by-step explanation:

A function is called a quadratic function if the highest degree of the function is 2.

The simplified form of given functions are:

P(x)=2x(x^2+6)+1=2x^3+12x+1

The highest degree of the function is 3, therefore P(x) is not a quadratic function.

m(x)=-4(x+3)-2=-4x-12-2=-4x-14

The highest degree of the function is 1, therefore m(x) is not a quadratic function.

t(x)=-8x^2(x^2-6)+1=-8x^4+48x^2+1

The highest degree of the function is 4, therefore t(x) is not a quadratic function.

h(x)=3x(x-2)-4=3x^2-6x-4

The highest degree of the function is 2, therefore h(x) is a quadratic function. Option 4 is correct.

snow_tiger [21]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In this question some information is missing that's why we explain "operating expenses".  

The Operating costs are paid in the business transactions and include property taxes, materials, stock costs, marketing, salary, health coverage, and R&D investments.

  • For other companies, these expenses are unavoidable and made mandatory. This cost is primarily important because it helps to evaluate the price effectiveness of the company as well as its inventory control.
  • It also shows the costs and requires a consulting company needs to be making to maximize income, which would be a company's main objective.

<span>a.       </span>Let m = be the number of miles driven

Cost of NYC rentals: 525 + 0.21m

Cost of Metro Trucks: 585 + 0.13m

 

<span>b.      </span>525 + 0.21m = 850

0.21m = 325

M = 1,548 miles

<span>c.       </span>Initial cost for NYC rentals = $525

Initial cost for Metro Trucks = $585

<span>d.      </span>NYC rentals: 525 + 0.21 (500) = $630

Metro Trucks rentals: 585 + 0.13 (500) = $650

<span>e.      </span>525 + 0.21m = 585 + 0.13m

0.21m – 0.13m = 585 – 525

0.08m = 60

m = 750 miles
