\( f(x)=\frac{x-1}{x+3} \); \( \operatorname{sor} D_{f}=? \)

What effect does multiplying the function \( f(x) = 3^x \) by -1 have on its graph? Describe any transformations.

1. If \( f(x)=\left\{\begin{array}{lll}-x^{2}-3 x & x \leq-1 \\ 2 x+3 & -1<x \leq 2\end{array}\right. \), computer the following \( \begin{array}{llll}\text { (a) } f(-3)= & \text { (b) } f\left(\frac{1}{2}\right)= & \text { (c) } f(-1)= & \text { (d) } f(3)\end{array} \)

Find the range of the function: \( y=x^{2}-3 x \)

Describe how the end behavior of a polynomial function changes based on its degree and leading coefficient.

Q8. Graphically, approximate the solutions of (a) \( e^{\frac{x}{3}}=2 e^{-x}, \quad \) (b) \( 4-\ln (2 x)=e^{x} \). [The End]
