Evaluating Functions: Key Concepts and Techniques

What is the name of the function in the notation f(x)?

• 3x+2

• x

• f(x)

• f

In the function notation f(x), what does 'x' represent?

• Output

• Input

• Function name

• Constant

How do you pronounce f(x)?

• f times x

• f divided by x

• f of x

• f plus x

If f(x) = 3x + 2, what is f(3)?

• 5

• 8

• 11

• 9

What does the entire notation f(x) represent?

• Variable

• Output

• Input

• Function name

When given a set of domain values, what is the easiest way to evaluate the function?

• Using a graph

• Guessing

• Using a T-chart

• Using a table

What is the range of g(t) = |6t - 8| for the domain {-1, 0, 1, 2, 3}?

• {14, 8, 2, 4, 10}

• {-14, -8, -2, -4, -10}

• {0, 1, 2, 3, 4}

• {-1, 0, 1, 2, 3}

If the domain is given as a set, how should the range be presented?

• As a graph

• As a table

• As a set

• As a list

For the function h(a) = a^2 - 3, what is the range for the domain -2 < a ≤ 3?

• [-3, 6]

• [-2, 9]

• [-2, 6]

• [-3, 9]

How do you determine if a range value is included when given a compound inequality?

• Check if the output value is positive

• Check if the input value is negative

• Check if the input value is in the domain

• Check if the function is linear
