Ask the student a question, and give any hints about how they should answer this part.
What is the equation of this curve?
-
$y=\simplify[unitFactor,fractionNumbers]{{a} sin({b}x+{c})+{d}}$
-
$y=\simplify[unitFactor,fractionNumbers]{{a} sin({1/b}x+{c})+{d}}$
-
$y=\simplify[unitFactor,fractionNumbers]{-{a} sin({b}x+{c})+{d}}$
-
$y=\simplify[unitFactor,fractionNumbers]{{2a} sin({b}x-{c})+{d}}$
-
$y=\simplify[unitFactor,fractionNumbers]{{a+1} sin({b}x-{c})+{2*d}}$
-
$y=\simplify[unitFactor,fractionNumbers]{{a} sin({2*b}x+{c})+{d}}$
