Work each problem related to linear functions. (a) Evaluate \(f(-2)\) and \(f(4)\) (b) Graph \(f\). How can the graph of \(f\) be used to determine the zero of \(f ?\) (c) Find the zero of \(f\) $$f(x)=x+2$$

Write the slope-intercept form of the line that passes through the given point with slope \(m .\) $$\text { Through }\left(\frac{1}{4}, \frac{2}{3}\right), m=\frac{1}{2}$$

Find the zero of the finction \(f\). Do not use a calculator. $$f(x)=1.5 x+2(x-3)+5.5(x+9)$$

Using the variable \(x,\) write each interval using set-builder notation. $$(-\infty,-1]$$

If \(c\) is a zero of the linear function \(f(x)=m x+b, m \neq 0\), then the point at which the graph intersects the \(x\) -axis has coordinates (______,_______)

Why is it not possible to write a slope-intercept form of the equation of the line through the points \((12,6)\) and \((12,-2) ?\)
