Across
  1. 4. two lines that run side by side. They have the same slope.
  2. 6. The solution to the factored form. Also called the zeros and x-intercept
  3. 9. a problem with numbers and/or letters but does not contain an = sign.
  4. 10. _____Function-A parabola that makes a ∩ or U shape graph.
  5. 13. two lines that cross making four 90̊ angles. They have the opposite reciprocals. (Opposite sign, flipped fraction)
  6. 16. Where it crosses the y-axis. The starting point. The original, beginning value
Down
  1. 1. where the function (graph) crosses the x-axis. It is called zeros, solution, and roots.
  2. 2. rate of Change, rise/run, When it is in y=mx+b it must touch the x, m.
  3. 3. a function that uses the >,≥,<,≤ (alligator mouths) allowing multiple values to make the statement true. When on a graph it is the shaded area.
  4. 5. the y values of the graph that stretches from bottom to top.
  5. 7. the x values of the graph that stretches from Left to Right.
  6. 8. _____Function-Line. Parent function is f(x)=x
  7. 11. an expression that contains an = sign. Use Menu 3,1-Nsolve to solve.
  8. 12. The value that makes the statement true. Also called the x-intercept
  9. 14. ______Variation-y=mx or y=kx. It is a linear function that goes through the origin. The y-intercept is 0.
  10. 15. Where the function (graph) crosses the x-axis.
