Exam 1

  1. Question

    Select each of the true statements from the following:


    1. The derivative of G(x)=2x9G(x)=2x^9 is 2x102x^10
    2. The derivative of G(x)=(2x+9)(19x+15)G(x)=(2x+9)(19x+15) is 2192 \cdot 19

    Solution

    1. False. According to the power rule the derivative of G(x)=axrG(x)=ax^r is G(x)=raxr1G^'(x)=rax^{r-1}
    2. False. According to the power rule the derivative of G(x)=axrG(x)=ax^r is G(x)=raxr1G^'(x)=rax^{r-1}
