1. 1. Population Project Germany By Brittany Beck
2. 2. Linear EquationFind two points then plug it into the equations. The equation is When you ﬁnd the answer to the ﬁrst equation plug it into m in the second equation.
3. 3. Graph Straight Line Chart 1 90000000 67500000 I put zero down asthe ﬁrst year when it 45000000 is actually 1850. Year 22500000 0 0 50 100 150 200 Prediction-91,087,752
4. 4. WorkEquation
5. 5. Quadratic Equation You have toﬁnd A,B and C. The Equation is f(x)=Ax 2 +Bx+C You plug in your points. Then you solve for A B and C
6. 6. Chart Curve line Chart 2 90000000 67500000 45000000 Year 22500000Predictio n--594,5 33,44 9.606 0 0 50 100 150 200
7. 7. Work
8. 8. LogarithmicEquation x y=ab You get two points and plug it into the equation. Then you put the two equations together and solve.
