Question statement

Estoy pensando en una función, ¡pero no te diré lo que es! Pero:

Es al menos dos veces diferenciable.
Le diré el valor de la función en cualquier lugar que solicite, con tres decimales. Puedes usar el cuadro de abajo para informarme. (Es posible que deba esperar un poco para que se cargue).

{geogebra_applet ('ufgKrAzb', defs)}

Give any introductory information the student needs.

			Name	Type	Generated Value

a	integer	1
b	integer	3
defs	list	Nested 4×2 list
c	integer	1
d	integer	2
x_0	rational	-27/10
df	rational	667/100
ddf	rational	-51/5

Automatically regenerate variables?

JME function reference

Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

→ Used by:

ddf
defs
df

"Unnamed part" → "Gap 0." - Minimum accepted value
"Unnamed part" → "Gap 0." - Maximum accepted value

Parts

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Suppose I reveal that the function is a cubic, so that $f(x) = a x^3 + b x^2 + c x + d$ . I will also tell you that $\{a,b,c,d\} \subset \mathbb{Z}$ . Calculate the parameters $a$ to $d$ .

$a =$ Gap 0.

$b =$ Gap 1.

$c =$ Gap 2.

$d =$ Gap 3.

Advice

Give a worked solution to the whole question.

Use this tab to check that this question works as expected.
