Match choices with answers
Ask the student a question, and give any hints about how they should answer this part.
-
f(x)={c[0]}x2+{c[1]}x3−{c[2]}x4
-
f(t)={c[3]}t3−{c[4]}t2+{c[5]}
-
g(x)={c[6]}x2+{c[7]}x
-
f(x)={c[8]}
-
g(x)=1{c[9]}
-
Not a polynomial
-
polynomial of degree 0 (constant)
-
polynomial of degree 1 (linear)
-
polynomial of degree 2 (quadratic)
-
polynomial of degree 3 (cubic)
-
polynomial of degree 4 (quartic)
For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
