1) Let x=0.565656...

2) Thus 100x=56.565656...

3) Subtracting equation 1) from 2) gives:

99x=56

4) Rearrange for x:

x=56/99, Also x...

To sketch a polynomial function (a polynomial is a function involving powers of x, for example y = x³ + 2x² - 13x + 10):

1. Start by differentiating the function to ...

Step 1: To differentiate an equation there is a simple rule to follow. For y=axⁿ dy/dx=anx^n-1. so for an example y=x³, dy/dx=3x^2. Therefore we just apply thi...
