Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Answer:
a) the initial value is $125, and it represents the cost Navin has to pay in the beginning
b) the rate of change is $20 per month, and it represents the cost he has to pay per month
c) linear; the equation for it is y = 20x + 125
d) The rate of change is constant because each month, Navin always has to pay $20.
e) This is <u>partial variation</u> because the equation y = 20x + 125 doesn't follow y = kx
