Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is  y  =  5sin3x

Step-by-step explanation:

From the question we are told that  

   y =  c_1\ cos3x + c_2 \  sin 3x

given that y(0) =  0

We have that  

     c_1\ cos3(0) + c_2 \  sin 3(0)  =  0

=>   c_1 =  0

This means that

           y  =  c_2 \  sin 3x

We also given that

          y[\frac{\pi}{6} ] =  5

So  

         c_2  sin (3 *  \frac{\pi}{6} )  =  5

=>    c_2  =  5

Hence  

     y  =  5sin3x

Given f of x equals 5 times x minus 6 for x less than 3, equals x squared for x between 3 and 5 inclusive, and equals 2 times x
konstantin123 [22]

Answer:

<em>D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real number</em>s.

Step-by-step explanation:

Find the complete diagram attached

First we need to get the derivative of the functions

For the function f(x) = 5x - 6

Using the formula

If f(x) = axⁿ

f'(x) = naxⁿ⁻¹

For the function f(x) = 5x - 6

f'(x) = 1(5)x¹⁻¹

f'(x) = 5x⁰

f'(x) = 5

For the function f(x) =x²-2

f'(x) = 2x²⁻¹

f'(x) = 2x

For the function f(x) = 4x+10

f'(x) = 1(4)x¹⁻¹

f'(x) = 4x⁰

f'(x) = 4

Get the domain

The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.

Hence Option D is correct
