Week {11} – Precalculus 11 – {Inequalities}

My biggest mistake of the week was thinking that inequalities show the equation on the graph instead of the range for things, one i realised how to actually do it it was a lot easier. the steps for how to find the inqeualities are the following

  • Step 1: simplify the inequality so that it is in vertex form
  • Step 2: choose a test point and determine whether is will be true or false
  • Step 3: insert this test point into the original equation and determine whether it is true or false
  • step 4: depending on whether it is true or false, shade the inside or the outside of the parabola
