Answer:
(3, 0 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
= -
y = 5x² - 30x + 45 ← is in standard form
with a = 5, b = - 30 , then
= -
= 3
Substitute x = 3 into the function for corresponding value of y
y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0
vertex = (3, 0 )

In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:
And the equation that represents the same company's yearly expenses is:
The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:
Operating:
Simplifying, the profit function for this company is:
