Front

What does it mean to evaluate a function at a given point?

Back

Evaluating a function at a point means substituting the input value into the function's equation to find the output value.

Front

How do you represent a situation with inequalities?

Back

To represent a situation with inequalities, identify the variables and their relationships, then express the constraints using inequality symbols (>, <, ≥, ≤).

Front

How do you solve a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side of the inequality sign, applying the same operations as you would for an equation, but reverse the inequality sign if you multiply or divide by a negative number.

Front

How do you simplify the expression @@ oot{20} imes oot{26}@@?

Back

First, combine the radicands: @@ oot{20 imes 26} = oot{520}@@. Then simplify if possible.

Front

What is the relationship between the slope and the steepness of a line?

Back

The slope of a line indicates its steepness; a larger absolute value of the slope means a steeper line.
