What?? I am very sorry, but this is confusing.
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.
Step-by-step explanation:
Answer:
y³ + x³ = 1
First, differentiate the first time, term by term:
↑ we'll substitute this later (4th step onwards)
Differentiate the second time:
Answer:
Step-by-step explanation:
5 3/7= 38/7 (move the wholes into the fraction)
2 1/5=11/5
38/7- 11/5 we need the common denominator=35
190/35 -77/35= 113/35
=3 8/35
