Part 1 of 3
The graphs of two polynomials $p$ and $d$ are shown in the accompanying figure. Answer each of the following for the rational function $f=\frac{p}{d}$ :
a. Find the domain of $f$.
b. Find the $x$-intercept(s) of $f$.
c. Sketch the graph of $f$.
a. The domain of $f$ is
(Type your answer in interval notation.)

Step 1 ：The domain of a rational function is all real numbers except where the denominator is zero. In this case, the denominator is the function $d$. We need to find the x-values where $d$ is zero. However, without the accompanying figure or the explicit functions for $p$ and $d$, it's impossible to provide a specific answer.

Step 2 ：If we had the explicit functions for $p$ and $d$, we could set $d$ equal to zero and solve for $x$ to find the values that are not in the domain of $f$.

Step 3 ：For example, if $d(x)=x^2-4$, we would set this equal to zero and solve for $x$:

Step 4 ：The output would be $[-2,2]$, meaning that the domain of $f$ is all real numbers except -2 and 2. In interval notation, this would be $(-\mathrm{\infty },-2)\cup (-2,2)\cup (2,\mathrm{\infty })$.

Step 5 ：$\boxed{{\displaystyle \text{Final Answer: Without the explicit functions for }p\text{ and }d\text{ or the accompanying figure, we cannot provide a specific answer. However, the general process to find the domain of a rational function is to set the denominator equal to zero and solve for }x.\text{ The domain of the function is all real numbers except the solutions to this equation.}}}$
