Final answer:
To find a quadratic function with zeros at -4 and -3, we can use the fact that the zeros are the solutions to the quadratic equation. The quadratic function would be f(t) = a(t + 4)(t + 3).
Step-by-step explanation:
To find a quadratic function with zeros at -4 and -3, we can start by using the fact that the zeros are the solutions to the quadratic equation. Both methods result in calculating the total cost of the gifts. However, Dani's method adds the costs together before multiplying by seven, while Chris's method multiplies each cost by seven and then adds them together. Both methods will yield the same answer as long as the individual costs are not different. The quadratic equation can be written as f(t) = a(t - x)(t - y), where x and y are the zeros. In this case, the quadratic function would be f(t) = a(t - (-4))(t - (-3)). We can simplify this to f(t) = a(t + 4)(t + 3).
