What does the value of $$b$$ in $$f(x) = a \times b^x$$ indicate?

The value of $$b$$ indicates the growth or decay factor. If $$b > 1$$ , the function grows; if $$0

What does the initial value in an exponential function represent?

The initial value in an exponential function, represented by $$a$$ in $$f(x) = a \times b^x$$ , indicates the starting amount before any growth or decay occurs.

How can you interpret the value of $$f(1)$$ in an exponential growth function?

The value of $$f(1)$$ in an exponential growth function represents the amount after one time unit has passed, showing the effect of growth over that period.

What is the domain of an exponential function?

The domain of an exponential function is all real numbers, represented as $$(-\text{∞}, \text{∞})$$ .

What is the range of an exponential function?

The range of an exponential function is all positive real numbers, represented as $$(0, \text{∞})$$ .

How do you determine the growth rate from an exponential function?

The growth rate can be determined from the base $$b$$ in the function $$f(x) = a \times b^x$$ . The growth rate is $$b - 1$$ .

What does the equation $$f(x) = 245(1.12)^x$$ represent in a real-world context?

This equation represents a situation where a quantity (e.g., bacteria) increases by 12% each time unit (e.g., day), starting from an initial amount of 245.

What is the significance of the constant in the equation of an exponential function?

The constant in the equation of an exponential function represents the initial value or starting amount before any growth or decay occurs.

How can you graph an exponential function?

To graph an exponential function, plot points for various values of $$x$$ , noting the y-intercept, asymptote, and the general shape of the curve, which rises or falls steeply.

What does the base of an exponential function represent?

Back

The base of an exponential function determines the rate of growth or decay. If the base is greater than 1, the function represents exponential growth. If the base is between 0 and 1, it represents exponential decay.

What is an asymptote in the context of exponential functions?

Back

An asymptote is a line that the graph of a function approaches but never touches. For exponential functions, the horizontal asymptote is typically the x-axis (y=0) for decay functions.
