1. For the pair of functions, determine the domain of f + g.f(x) = 2x + -9, g(x) = 4x + -3. 2. For the pair of functions, determine the domain of f + g.f(x) = 4x + 3, g(x) = 3x + 8. 3. Find the slop

1. For the pair of functions, determine the domain of f + g.f(x) = 2x + -9, g(x) = 4x + -3.

2. For the pair of functions, determine the domain of f + g.f(x) = 4x + 3, g(x) = 3x + 8.

3. Find the slope then describe what it means in terms of the rate of change of the dependent variable per unit change in the independent variable.The linear function f(x) = 3.8x + 22 represents the percentage of people, f(x), who graduated from college x years after 1998.

4. .A vendor sells hot dogs and bags of potato chips. A customer buys 2 hot dogs and 3 bags of potato chips for $6.25. Another customer buys 4 hot dogs and 3 bags of potato chips for $10.25. Find the cost of each item.
