[2] Yes, and a correct explanation is provided, such as showing that the discriminant is
negative and interpreting that result as meaning there are no real solutions.
[1] A wrong answer is stated, resulting from one computational or conceptual error, but an
appropriate explanation is provided.
[0] Yes, with no work shown or explanation provided.
[0] Completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by
an obviously incorrect procedure.

[2] b(t) = 1150(2)
and 1,177,600, and correct work is shown.
t
[1] b(t) = 1150(2)
, but one computational error is made evaluating b(10), such as evaluating
t
1150(2)(10).
[1] Appropriate work is shown, but one computational or conceptual error is made writing the
function, such as b(t) = 1150(2)t, but the incorrect function is correctly evaluated for t = 10.
[1] b(t) = 1150(2)
, but no further correct work is shown.
t
[0] Completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by
an obviously incorrect procedure.
31
[2] Domain: 0 ≤ x ≤ 9, or equivalent; range: 0 ≤ y ≤ 60, or equivalent; 3 < x < 4, or equivalent,
and a correct explanation is provided, such as stating that the slope (or rate of change) is
the steepest (or greatest) during that interval.
[1] Appropriate work is shown, but one computational error is made.
[1] Appropriate work is shown, but one conceptual error is made, such as writing the domain
as 0 ≤ y ≤ 60 and range 0 ≤ x ≤ 9, but with a correct interval and explanation provided, or
stating only the domain or range, but with a correct interval and explanation provided.
[1] Correct domain, range, and interval stated, but with no explanation provided for the
interval.
[1] Correct domain and range stated, but no further correct work is shown.
[1] Correct interval and explanation provided, but either domain or range is stated incorrectly
or missing.
[0] Completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by
an obviously incorrect procedure.
