Given the function \( f(x)=-4 x-8 \), find the following values. \( \begin{array}{l}\text { a. } f(-2) \\ \text { a. } f(-2)=0 \text { (Simplify your answer.) } \\ \text { b. } f(s)=\square \text { (Simplify your answer. Do not factor.) }\end{array} \)

Question 3 (1 poing Is the equation for the graph of \( f(x)=-x^{2}-5 \) reflected across the \( y \)-axis the same equation? True False

Write the expression as a sum and/or difference of logarithms. Express powers as factors. \( \log _{7}(2401 \mathrm{x}) \) \( \log _{7}(2401 \mathrm{x})=\square \) (Type an exact answer in simplified form.)

Which shows \( f(x)=|x-24| \) expressed as a piecewise-defined function? \[ f(x)=\left\{\begin{array}{l}x-24, x \geq 24 \\ -x+24, x<24\end{array}\right. \] \[ f(x)=\left\{\begin{array}{l}x-24, x \geq-24 \\ -x+24, x<-24\end{array}\right. \] \( f(x)=\left\{\begin{array}{l}x-24, x \geq 0 \\ -x+24, x<0\end{array}\right. \) \( f(x)=\left\{\begin{array}{l}x-24, x \geq 1 / 24 \\ -x+24, x<1 / 24\end{array}\right. \)

IV. Solve for the roots of SOLUTION on the space on the back of this paper \( 24-25.4 x-81=0 \) \( 26-27 x+12 x=-35 \)

Evaluate the following function at the values \( -3,9 \), and \( a \). \( f(t)=\frac{t}{t+1} \)
