- Find the y-intercept
- Find the roots (i.e. x - intercepts)
- Determine where the function increases and where it increases, along with the maximum and minimum values.
- Determine where the function changes concavity along with the inflection points.
- Determine the special points, where the value of the function is not defined and try to find the limit when the value of x approachs to this values
- Determine the limits of the function when x approachs to positive infinity and negative infinity
- For some of those steps you need to know some concepts of calculus: limits and derivatives along with the rules that let you know if a point is a maximum, a minimum or an inflection point.
With that information you can sketch a polynomial function.

Answer:
C: Elastic to Mechanical
Step-by-step explanation:
Dear Megan561, the two denominators are 4 and 14.
|AB|^2 = |AC|^2 + |CB|^2 - 2|AC||CB|cos70° = 50^2 + 70^2 - 2(50)(70)cos 70° = 2,500 + 4,900 - 7,000cos 70° = 7,400 - 2,394.14 = 5,005.86
|AB| = sqrt(5,005.86) = 70.8 feet.
Therefore, the houses are 70.8 feet apart.
