Which of the following is the derivative of
 $y=x^3+5$  

•  $\frac{\text{d}x}{\text{d}y}=6x^2$  

•  $\frac{\text{d}x}{\text{d}y}=3x^2$  

•  $\frac{\text{d}x}{\text{d}y}=3x^2+5$  

•  $\frac{\text{d}x}{\text{d}y}=6x^2+5$  

If the limit as for a function f(x) is equal to f(c), the function is continuous.

• True

• False

 $\left(5x^2+2x+4\right)^3$ 
Find the derivative of the following function:

•  $3\left(5x^2+2x+4\right)$  

•  $3\left(10x^2+2\right)$  

•  $750x^5+24x^2$  

•  $3\left(5x^2+2x+4\right)^2\left(10x+2\ \right)$  

The first rule that we would use to find the derivative of  $f\left(x\right)=x\left(1+x\right)^{12}$ is the product rule.

• True

• False
