Math 1 - Unit 2A - 2.4.1 KEY FEATURES

Front

What is the y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis. For example, in the point (0,7), the y-intercept is 7.

Front

Find the interval(s) of increase of the graph shown.

Back

The interval of increase is the range of x-values where the function is rising. For example, -4 < y < -2 indicates the function is increasing between these y-values.

Front

What is the DOMAIN of this function?

Back

The domain of a function is the set of all possible input values (x-values). For this function, the domain is -∞ < x < ∞.

Front

Does the graph have a maximum or minimum?

Back

A graph can have a maximum (highest point) or minimum (lowest point). In this case, the graph has a maximum.

Front

What is the DOMAIN of this graph?

Back

The domain of this graph is -7 < x < 5, meaning x can take any value between -7 and 5, not including -7 and 5.

Front

What does it mean for a function to be increasing?

Back

A function is increasing when its output values (y-values) rise as the input values (x-values) increase.

Front

What is a maximum point on a graph?

Back

A maximum point is the highest point on a graph within a given interval.

Front

What is a minimum point on a graph?

Back

A minimum point is the lowest point on a graph within a given interval.

Front

How do you determine the y-intercept from a function's equation?

Back

To find the y-intercept, set x = 0 in the function's equation and solve for y.

Front

What is the significance of the domain in a function?

Back

The domain indicates the set of input values for which the function is defined.
