Consider the function f(x) = x^{2/3} on the interval [-1,8].

1 answer:

5 0

The right option is (c). The Mean Value Theorem does not apply since f(x) is not differentiable on (-1,8). Because the derivative of f is 2/3 x^(-1/3) which is undefined at x=0.So, that would imply that it is not differentiable along the interval.

53 - 9y = 1 -7.2 + 2y = -5

telo118 [61]

Answer:

1.1, -5

Step-by-step explanation:

53 - 9y = 1

from equation i

53-9y = 1

-9y= 1-53 = -52

y = -52/-9= 52/9 = 5⁷/₉

-7.2 + 2y = -5

add 7.2 to both sides

2y= -5+7.2 = 2.2

y= 2.2/2 = 1.1

Rewrite the quadratic function in intercept or factored form y=x^2+7x+10

Nataly [62]

Answer: $y=(x+2)(x+5)$

Step-by-step explanation:

1. You have the following the quadratic equation given in the problem above:

$y=x^{2}+7x+10$

2. To factor the quadratic function, you must find two number that when you add them you obtain 7 and when you multiply them you obtain 10. These numbers would be 2 and 5.

3. Therefore, keeping this on mind, you can rewrite the function in the following intercept form:

$y=(x+2)(x+5)$
