5.2 Part 2: zero step and rule

Front

What is the zero step in a sequence of steps?

Back

The zero step is the initial step or starting point before any other steps are taken.

Front

What is a function rule?

Back

A function rule is an equation that describes the relationship between input (x) and output (y) values.

Front

If the function rule is y = 4x + 1, what is the output when x = 2?

Back

y = 4(2) + 1 = 9.

Front

If the function rule is y = 3x + 4, what is the output when x = 1?

Back

y = 3(1) + 4 = 7.

Front

What does the '4' represent in the function rule y = 4x + 1?

Back

The '4' is the coefficient of x, indicating the rate of change or slope of the function.

Front

What does the '1' represent in the function rule y = 4x + 1?

Back

The '1' is the y-intercept, indicating the value of y when x = 0.

Front

How do you find the zero step if steps 1-3 are given?

Back

You identify the step that comes before step 1, which is the zero step.

Front

What is the significance of identifying the zero step in a sequence?

Back

Identifying the zero step helps in understanding the starting point of a process or function.

Front

If the function rule is y = 3x + 1, what is the output when x = 0?

Back

y = 3(0) + 1 = 1.

Front

What is the general form of a linear function?

Back

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