Yes, but as you plug whatever numbers you have into the equation parentheses won't be necessary.

C would be the correct answer.

All of the numbers are integers, which is a subset in rational numbers. The numbers (0-3) are all whole numbers. The whole numbers are a part of integers, completing the chart.

Given the function f(x)=x^4+8x^3+18x^2+7 determine the absolute minimum value of f on the closed interval [-4, 1].

Blababa [14]

Answer: 7

Step-by-step explanation:

To find the absolute minimum we must first take the derivative of the function and find where it equals zero. From there we can use the first derivative test to find where our possible minimum is. We then will test each endpoint and compare for the minimum for this function.

$f(x)=x^4+8x^3+18x^2+7\\f'(x) = 4x^3+24x^2+36x\\\\4x^3+24x^2+36x = 4x(x^2+6x +8)\\\\x = 0\\x = -4\\x = -2\\\\f(-4) = 39\\f(-2) =31\\f(0) = 7\\f(1) = 34$

The lowest value is 7. The absolute minimum of this function is 7. If you were to graph it, we'd see that the graph reflects that as well.
