match each function to its antiderivative, where t > 3 and c is a constant. antiderivative function h(t)=ln(12t² - 12)+c h(t)=(3t² - 3)/(t³ - 3t) h(t)=ln(t⁴ - 6t²)+c h(t)=(4t² - 12)/(t³ - 6t) h(t)=ln(4t³ - 12t)+c h(t)=(2t)/(t² - 1)
Answer
Explanation:
Step1: Recall the chain - rule for derivatives of logarithmic functions
The derivative of $\ln(u)$ with respect to $t$ is $\frac{u'}{u}$, where $u$ is a function of $t$.
Step2: For $H(t)=\ln(12t^{2}-12)+C$
Let $u = 12t^{2}-12$, then $u'=24t$. So $\frac{dH}{dt}=\frac{24t}{12t^{2}-12}=\frac{2t}{t^{2}-1}$.
Step3: For $H(t)=\ln(t^{4}-6t^{2})+C$
Let $u=t^{4}-6t^{2}$, then $u' = 4t^{3}-12t$. So $\frac{dH}{dt}=\frac{4t^{3}-12t}{t^{4}-6t^{2}}=\frac{4t^{2}-12}{t^{3}-6t}$.
Step4: For $H(t)=\ln(4t^{3}-12t)+C$
Let $u = 4t^{3}-12t$, then $u'=12t^{2}-12$. So $\frac{dH}{dt}=\frac{12t^{2}-12}{4t^{3}-12t}=\frac{3t^{2}-3}{t^{3}-3t}$.
Answer:
$H(t)=\ln(12t^{2}-12)+C$ matches $h(t)=\frac{2t}{t^{2}-1}$ $H(t)=\ln(t^{4}-6t^{2})+C$ matches $h(t)=\frac{4t^{2}-12}{t^{3}-6t}$ $H(t)=\ln(4t^{3}-12t)+C$ matches $h(t)=\frac{3t^{2}-3}{t^{3}-3t}$
