Intercepts Zeros Asymptotes 0E083F
1. **Problem Statement:** Given the function $f(x) = 3x + 3$, find:
(a) the $x$-intercept and $y$-intercept,
(b) zeros of the function,
(c) asymptotes.
2. **Formula and Rules:**
- The $x$-intercept occurs where $f(x) = 0$.
- The $y$-intercept occurs where $x = 0$.
- Zeros of the function are values of $x$ where $f(x) = 0$.
- Asymptotes are lines the graph approaches but never touches; linear functions have no asymptotes.
3. **Finding the $x$-intercept:**
Set $f(x) = 0$:
$$3x + 3 = 0$$
Subtract 3 from both sides:
$$3x = -3$$
Divide both sides by 3:
$$x = -1$$
So, the $x$-intercept is at $(-1, 0)$.
4. **Finding the $y$-intercept:**
Set $x = 0$:
$$f(0) = 3(0) + 3 = 3$$
So, the $y$-intercept is at $(0, 3)$.
5. **Finding zeros:**
Zeros are where $f(x) = 0$, which we already found as $x = -1$.
6. **Asymptotes:**
Since $f(x)$ is a linear function, it has no asymptotes.
**Final answers:**
(a) $x$-intercept: $(-1, 0)$, $y$-intercept: $(0, 3)$
(b) Zero: $x = -1$
(c) No asymptotes
