You an't solve it further. Is this what you mean? X to the fourth power?

Answer:

[-4,3]

Step-by-step explanation:

The domain is the left-right (horizontal) extent of the function. The dots at the end of the continuous line are solid, so the brackets on the interval are square brackets.

The left dot is at x=-4; the right dot is at x=3, so the domain is ...

The profits of mr cash’s company is represented by the equation p(t)=-3t^2+18t-4, where p(t) is the amount of profit in hundreds

Anika [276]

Answer:

$2300000- max profit
5.77 years into operation - zero profit time

Step-by-step explanation:

Given function:

p(t)= -3t^2 + 18t - 4

It is a quadratic function with general form of y = ax^2 + bx + c

It opens down if a < 0 and gets maximum value at vertex which is determined at x = -b/2a

For the given function vertex is:

t = -18/-3*2 = 3

Maximum value of p is:

p(3) = -3*3^2 + 18*3 - 4 = -27 + 54 - 4 = 23 ($2300000)

The time when profit is zero:

-3t^2 + 18t - 4 = 0
3t^2 - 18t + 4 = 0
t = (18 ± √18² - 4*3*4)/2*3 = (18 ± √276)/6 = (18 ± 16.61)/6
t = (18 - 16.61)/6 = 0.23 this is the time when company has just started to make profit, it is not applicable as is the past time
t = (18 + 16.61)/6 = 5.77 years into operation, after this time there will be no profit
