Answer:
The vertex is (−3, −1), the domain is all real numbers, and the range is y ≤ −1
Step-by-step explanation:
f(x) = −2(x + 3)^2 − 1
The vertex form is
f(x) = a ( x-h) ^2 + k where ( h,k) is the vertex
f(x) = −2(x - -3)^2 − 1
The vertex is ( -3,-1) is the vertex
The domain is the values that x can take and x can take all real numbers
The vertex is the maximum since a is negative so the range is all values less than -1
y ≤ −1
Answer:
C = 53D + 99
Step-by-step explanation:
The cost (C) is equal to $53 per day (53 multiplied by the number of days, D) plus the fixed deposit (+ 99)
Expressed as a linear equation below
C = 53D + 99
Answer:
That is known as a Vertex
