Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
Answer:
10
Step-by-step explanation:
(50-32)*5/9=10
the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.
A place value is the value of a number in whatever spot it is in for example 100,050 The value of the one is one hundred thousand and the value of the five is fifty
U(x)=-2x²+3
v(x)=1/x →→ range of (uоv)(x, BUT range (uov)(x = u(v(x)), then :
u(v(x)) = -2(1/x²) + 3 →→u(v(x)) = -2/x² + 3
The range of -2/x² + 3 = {x∈R/x≠0}
