Give the (a) \(x\) -intercept, (b) \(y\) -intercept, (c) domain, (d) range, and (e) slope of the line. Do not use a calculator. $$f(x)=x-4$$

Using interval notation, write each set. Then graph it on a number line. $$\\{x |-1

Write the slope-intercept form of the line that passes through the given point with slope \(m .\) Do not use a calculator. Through \((1,3), m=-2\)

For each set, list all elements that belong to the (a) natural numbers (b) whole numbers (c) integers (d) rational numbers (e) irrational numbers (f) real numbers $$\left\\{-6,-\frac{12}{4},-\frac{5}{8},-\sqrt{3}, 0,0.31,0 . \overline{3}, 2 \pi, 10, \sqrt{17}\right\\}$$

Find the zero of the function \(f\) $$f(x)=-3 x-12$$
