Topics 3-1 - 3-2 Review

Front

For the function f(x) = -3(x-1), find f(0).

Back

f(0) = -3(0-1) = 3.

Front

Evaluate f(-2) if f(x) = x + 3.

Back

f(-2) = -2 + 3 = 1.

Front

Is this mapping a function or not a function?

Back

A mapping is a function if each input has exactly one output.

Front

Let g(x)=9x+24, find g(3).

Back

g(3) = 9(3) + 24 = 51.

Front

What is the Range of a function?

Back

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

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the domain of a function?

Back

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

Front

How do you find the value of a function at a specific point?

Back

Substitute the specific point into the function's equation.

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
