Magazine Problem 14
Use function notation to write the equation of each line with the given slope and \(y\) -intercept. Slope \(\frac{1}{2} ; y\) -intercept \((0,-6)\)
Problem 15
Use function notation to write the equation of each line with the given slope and \(y\) -intercept. Slope 2: \(y\) -intercept \(\left(0, \frac{3}{4}\right)\)
Problem 15
Graph each piecewise-defined function. Use the graph to determine the domain and range of the function. $$g(x)=\left\\{\begin{array}{lll} {-2} & {\text { if }} & {x \leq 0} \\ {-4} & {\text { if }} & {x \geq 1} \end{array}\right.$$
Problem 15
