EOC Review #4

Front

What type of pattern do linear functions have?

Back

Linear functions add or subtract by the same number every time.

Front

What is the initial value in the function y=4(2)^x?

Back

The initial value is 4.

Front

Which equation is represented by the table?

Back

The equation is y = 40(1/2)^x.

Front

If the population of a species of insects doubles every year, how many insects will there be after 3 years if the function is f(x)=1600(2)^x?

Back

There will be 12,800 insects after 3 years.

Front

What is the y-intercept of the function y = 2x + 3?

Back

The y-intercept is 3.

Front

Define a linear function.

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a linear function represent?

Back

The slope represents the rate of change of the function, indicating how much y changes for a unit change in x.

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where a is a constant, b is a positive real number, and x is the exponent.

Front

How do you find the y-intercept of a function?

Back

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

Front

What is the general form of an exponential growth function?

Back

The general form is f(x) = a * b^x, where a > 0 and b > 1.
