If y=x^2 and x=(-8) then y =...
lutik1710 [3]

Answer:

-64

Step-by-step explanation:

If

y=x^2

and the x represents -8

Your answer will be -64

By saying that x=(-8)   all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it   y=(-8)^2

When you plug in negative 8 to the second power into the calculator your answer will be -64

I hope this helps king!

Find the value of the derivative (if it exists) at the indicated extremum. (If an answer does not exist, enter DNE.)
Liono4ka [1.6K]

Answer:

The answer is "0".

Step-by-step explanation:

Please find the correct question in the attached file.

Given value:

\to f(x) =\frac{x^2}{x^2+5}\\\\

Formula:

\bold{\frac{d}{dx} \frac{u}{v} = \frac{ v \frac{du}{dx} - u \frac{dv}{dx}}{v^2}}

\to f'(x) =\frac{(x^2+5) 2x -2x^3 (2x)}{(x^2+5)^2}\\\\\to f'(0) =\frac{(0^2+5)2(0) -4(0)^4}{(0^2+5)^2}\\\\\to f'(0) =\frac{(0)(5) -2(0)}{(5)^2}\\\\\to f'(0) =\frac{0 - 0}{(5)^2}\\\\\to f'(0) =\frac{0}{25}\\\\\to f'(0) = 0
