Semester #1 Practice Final (Part 1)(IM2) 24-25

Front

What is the average rate of change?

Back

The average rate of change of a function over an interval is the change in the function's value divided by the change in the input value over that interval.

Front

Calculate the average rate of change from 20 to 40 minutes if the output changes from 0 to -80 gallons.

Back

Average rate of change = (Change in output) / (Change in input) = (-80 - 0) / (40 - 20) = -4 gallons per minute.

Front

What is the simplified form of 2^3?

Back

8

Front

Back

It represents a V-shaped graph that opens upwards with the vertex at (-2, 0).

Front

How do you find the x-intercept of a graph?

Back

To find the x-intercept, set y = 0 and solve for x.

Front

Back

The x-intercept is (-2, 0).

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

Back

All real numbers.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex is the highest or lowest point on the graph of a quadratic function, depending on whether it opens upwards or downwards.
