Answer:

the k value is 6

Step-by-step explanation:

The form of a qruadratic equation is f(x)=a(x-h)^2 + k, so by comparing this to the function f(x)=-18(x-2)^2 + 6 we can see that K = 6, a = -18,and h = 2.

Consider the following function. f ( x ) = 1 − x 2 / 3 Find f ( − 1 ) and f ( 1 ) . f ( − 1 ) = f ( 1 ) = Find all values c in (

Answer:

(E)Nothing can be concluded.

Step-by-step explanation:

Given the function $f(x)=1-x^{\frac{2}{3}}$

$f(-1)=1-(-1)^{\frac{2}{3}}=1.5-0.86603i\\f(1)=1-1^{\frac{2}{3}}=1-1=0$

$f'(x)=-\dfrac{2}{3}x^{-\frac{1}{3}}\\f'(x)=-\dfrac{2}{3\sqrt[3]{x} }$

If the derivative is set equal to zero, the function is undefined.

Nothing can be concluded since $f(1)\neq f(-1)$ and no such c in (-1,1) exists such that $f'(c)=0$

THEOREM

Rolle's theorem states that any real-valued differentiable function that attains equal values at two distinct points must have at least one stationary point somewhere between them—that is, a point where the first derivative is zero.
