function value
The output assigned to a specified input by a function.
Substitute the input and report its output, not the input itself.

1–12 of 261 cards
construct / write
Create the specified mathematical object so it satisfies the supplied conditions.
Produce the requested function, equation, expression or model and verify it against the observations.
at least
The specified value is a lower bound and is included.
Use a greater-than-or-equal inequality, not a strict inequality.
cite the input-output evidence
Support a table-based conclusion with the actual relevant pairs or computations, while respecting whether the table is complete.
State the value or relationship shown by the representation; do not invent unlisted values.
graph intersection
A point where two graphs have the same output at the same input.
Report the requested input or coordinate and check the specified interval; a viewing window may hide other intersections.
input
A value supplied to a function, usually the independent variable.
Identify the independent quantity and its allowed values.
describe
State precise mathematical features or behavior in words or suitable notation.
Identify the relevant interval, direction or characteristic; do not substitute an unrelated calculation.
at most
The specified value is an upper bound and is included.
Use a less-than-or-equal inequality with the stated maximum.
constant second differences with equal input steps
Numerical evidence for a quadratic model includes equal input spacing and a nonzero constant second output difference.
Name equal input steps and provide the second-difference value; a finite table supports a model rather than proving global identity.
zero-finding tool
A numerical method for locating an input where a function's value is zero.
Check the original domain and search range; one returned root is not proof of a complete solution set.
output
The value a function assigns to an input, usually the dependent variable.
Identify the dependent quantity, with units if the context supplies them.
determine / find / identify
Provide the particular value, set or object the prompt requests; include reasoning when requested.
Read whether the target is an input, output, function, interval or parameter before answering.
