Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {-4, 0, 1, 2}.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {-4, -3, 1}.

Front

Back

Multiply both sides by -2: d - 8 = -24, then d = -16.

Front

What is the value of f(3) for the function f(x) = 2(x + 4) + 3?

Back

f(3) = 2(3 + 4) + 3 = 17.

Front

How do you evaluate f(x) = 7(x - 11) at x = 16?

Back

f(16) = 7(16 - 11) = 7(5) = 35.

Front

What are x-intercepts?

Back

X-intercepts are points where the graph of a function crosses the x-axis (y=0).

Front

What are y-intercepts?

Back

Y-intercepts are points where the graph of a function crosses the y-axis (x=0).

Front

What are the x- and y-intercepts of the function with intercepts (5,0) and (0,5)?

Back

X-intercept: (5,0), Y-intercept: (0,5).
