Answer:
y=54/7
Step-by-step explanation:
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
F1) 4 , F2) 16 Explanation add 4 after every number
It would be 1,300. When rounding, you'd need to look at the number to the right of the place you're rounding to. In this case, you're rounding to the hundreds place (the 2), so you look at the number to the right (7). To know if you round up or down use this:
Round down= 0-4
Round up= 5-9
