Actividad 1.1<br />Investigue sobre el tema de diferenciabilidad en un punto para encontrar los valores de "a" y "b" tales
Olegator [25]

Answer:

a = 8

b = -8

Step-by-step explanation:

You have the following function:

f(x)\\\\=at+b;\ \ t

A function is differentiable at a point c, if the derivative of the function in such a point exists. That is, f'(c) exists.

In this case, you need that the function is differentiable for t=2, then, you have:

f'(t)=a;\ \ \ \ t

If the derivative exists for t=2, it is necessary that the previous derivatives are equal:

f'(2)=a=4(2)\\\\a=8

Furthermore it is necessary that for t=2, both parts of the function are equal:

8(2)+b=2(2)^2-1\\\\16+b=8-1\\\\b=-8

Then, a  = 8, b = -8

What are 2 different equivalent fractions for LaTeX: \frac{2}{6}2 6 ? *In your answer, use a "/" as a fraction bar symbol. For e
Orlov [11]

Answer:

<em> 4/12 and 6/18</em>

Step-by-step explanation:

Given the fraction 2/6

We are to write  2 different equivalent fractions that are the same as 2/6

To do this, we will multiply the numerator and denominator of the fraction by same constant. Multiply the numerator and denominator by 2 will give;

2/6 * 2/2

= (2*2)/(6*2)

= 4/12

Also multiplying by a value of 3

= 2/6 * 3/3

= (2*3)/(6*3)

= 6/18

<em>Hence the 2 different equivalent fractions are 4/12 and 6/18</em>
