Find the domain and range of the function represented by the graph

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

Match each set of points with the quadratic function whose graph passes through those points

Given: tangent if m 1 = 30° and m = 20°, then m = 10 40 80
