STEPS:1) Pick x values (be strategic)
2) Plug those in x values in to get your y values
3) Use your values to create a Tchart
4) Use your Tchart to graph the function
5) Restrict your domain, if necessary.

ACT Practice:DMC Electronics Company builds 2 products: a DVD player and a VCR. Employees of the company can build a maximum of 150 DVD players per week and a maximum of 200 VCRs per week. No more than 250 products can be built per week. In the following inequalities, d represents the number of DVD players and v represents the number of VCRs. Which inequality expresses the constraint on the number of products build per week?A. d + v < 150
B. d +v > 200
C. d + v < 200
D. d + v > 250
E. d + v < 250
