Answer:
(b) 30
Step-by-step explanation:
The standard form of a quadratic is ...
y = ax^2 +bx +c
For such a function, the axis of symmetry is ...
x = -b/(2a)
Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...
x = -300/(2(-5) = 30
The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.
_____
Of course, a graphing calculator can display the maximum of the function easily.
Answer:
The domain for given function is
Step-by-step explanation:
Given :
We have to find the domain of the given function.
Domain of a function is defined as a set of value for which the value of function is real and defined.
Consider the given function
Since there is no points for x where the function f(x) is non defined.
Hence, whole number line is the domain for the given function.
In interval form it is written as
Thus, the domain for given function is
Is C g(x) = -X^2 -3
This is the answer
This is what we have:
what we want is for x to "stand alone": for this, we need to get rid of this 5. we can do this by multiplying both sides of the equation by 5:
if we both divide and mupliply the first numebr by 5, it just means 1, so we can skip it:
