Front

What type of function describes the value of an iPhone X that decreases by 14% each year?

Back

Exponential function.

Front

In the equation y = mx + b, what does 'b' represent?

Back

y-intercept (initial amount).

Front

In the equation y = mx + b, what letter represents the slope of the line?

Back

m.

Front

Write the explicit equation for a function that decreases by a factor of 1/3 starting from 27.

Back

f(x) = 27(1/3)^x.

Front

When graphing a continuous function, what should you do?

Back

Connect the dots.

Front

What is the general form of a linear function?

Back

y = mx + b.

Front

What does the slope 'm' indicate in a linear equation?

Back

The rate of change of y with respect to x.

Front

What is the difference between linear and exponential functions?

Back

Linear functions have a constant rate of change, while exponential functions have a variable rate of change that increases or decreases multiplicatively.

Front

How do you identify a linear function from a table of values?

Back

If the differences between consecutive y-values are constant, it is linear.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

m = (y2 - y1) / (x2 - x1).
