Answer:
maximum value : y = - 1 at (2, -1)
No local minimum
Step-by-step explanation:
The function y=−x^2+4x−5. is a downward opening parabola.
The local maximum is at the vertex
y = - (xx - 4x ) - 5
y = - (xx - 4x +4 - 4) - 5
y = - (xx - 4x + 4) + 4 - 5
y = -(x - 2)^2 - 1
vertex at (2, -1)
Answer:
Step-by-step explanation:
When doing the order of operations and you are put in a situation where you do two different operations, solve the problem from left to right.
In this case instead of doing 6*4 first do 24/6 first.
LnA +LnB= LnA.B
so we get <span>Log3(X-5)+log3(x+3)=Ln3(x-5)(x+3)=2 implies
</span>(x-5)(x+3)=2^3=8, so we can solve easily the quadratic equation
x^2-2x-23=0, there are two solution x=1 -sqrt(24), and x=1+sqrt(24)
