Evaluate Functions

Front

What does it mean to find f(2) in a function?

Back

Let x = 2.

Front

How do you read f(x)?

Back

f of x.

Front

For the function f(x) = 4x + 2, find x such that f(x) = 2.

Back

x = 0.

Front

If f(x) = 2x + 1, what does f(1) equal?

Back

f(1) = 2(1) + 1.

Front

What is f(6) for the function f(x) = 3x - 8?

Back

f(6) = 10.

Front

What is the general form of a linear function?

Back

f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope (m) represent in a linear function?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept (b) in a linear function?

Back

The y-intercept is the value of f(x) when x = 0.

Front

How do you evaluate a function at a specific value?

Back

Substitute the value into the function's equation.

Front

What is the output of f(x) = x^2 when x = 3?

Back

f(3) = 3^2 = 9.
