Answer:
max{x²-4x²+5} = 5 at x = 0
Step-by-step explanation:
1. Find the critical numbers by finding the first derivative of f(x), set it to 0 and solve for x.

We get:

So the critical number is x = 0.
2. Evaluate the first derivative by plugging in the critical number and see if the derivative is positive or negative on both sides:
is positive when the x < 0 (for example: -6*(-1)=+)
is negative when the x > 0 (for example: -6*(1)=-)
Therefore, you have a local maximum.
Now just get the Y value by plugging in the critical number in the original function. 
local maximum is (0,5)
Answer:
I NEED HELP! What are the dimensions of the rectangle shown below? Remember to use the axes on the coordinate grid to help you.
A coordinate grid is shown with scale from negative 14 to 0 to positive 14 on both x- and y-axes at increments of 2. A figure ABCD is shown with A at ordered pair negative 4, 4, B at ordered pair 10, 4, C at ordered pair 10, negative 4, and D at ordered pair negative 4, negative 4.
Step-by-step explanation:
R^2=(96/2)^2+14^2
r^2=2500
r=√2500
r=50
