Given f, of, x, equals, minus, 5, x, minus, 1*f*(*x*)=−5*x*−1, find f, of, minus, 1*f*(−1).

To find \( f(-1) \) given the function \( f(x) = -5x - 1 \), we substitute \( x = -1 \) into the function.

Let's calculate:

\[
f(-1) = -5(-1) - 1
\]

Now, simplify:

\[
f(-1) = 5 - 1 = 4
\]

So, \( f(-1) = 4 \).

2. Determine the value of \( x \) such that \( f(x) = 0 \) for \( f(x) = -5x - 1 \).
3. Evaluate \( f(x) \) when \( x = 2 \).
4. What is the y-intercept of the function \( f(x) = -5x - 1 \)?
5. Solve \( f(x) = 10 \) for \( x \) in the function \( f(x) = -5x - 1 \).

**Tip:** When working with linear functions, the coefficient of \( x \) represents the slope, and the constant term represents the y-intercept.
