Use the Leading Coefficient Test to determine the end behavior of the polynomial function. 7) \( f(x)=-x^{2}(x+1)(x+3) \)

Formula for standard error of the mean: \( s_{\bar{x}}=\frac{s}{\sqrt{n}} \) \[ t=\frac{\bar{X}-\mu}{s_{\bar{x}}} \] - Mean number of cases for geographic localities in Texas: 32.49 - Sample mean for San Marcos: 29.92 - Sample standard deviation for San Marcos: 5.12 - Sample size: 25

228. \( \left\{\frac{3}{5} \times\left[\left(\frac{1}{2}-\frac{1}{3}\right)^{2}: \frac{5}{24}+\frac{8}{15}\right] \times\left(1+\frac{1}{2}\right)^{2}+\left(1+\frac{1}{3}+\frac{1}{4}+\frac{1}{12}\right)\right\}: \frac{11}{3} \)

If the null hypothesis \( H_{0}: p=p_{0} \) is true, the of is \( \sqrt{\frac{p_{0}\left(1-p_{0}\right)}{n}} \)

8. Factoriza cada trinomio de la forma \( a^{2}+ \) mab \( +b^{2} \) con \( m \) diferente de 2 , por adición o sustracción. a. \( 25 a^{2}+54 a b+49 b^{2} \)

Find and simplify each of the following for \( f(x)=6 x^{2}-7 x+6 \) (A) \( f(x+h) \) (B) \( f(x+h)-f(x) \) (C) \( \frac{f(x+h)-f(x)}{h} \)
