Growth: b > 1, function increases | Decay: 0 < b < 1, function decreases.

Vertical Shifts: Affect the y-values, change the horizontal asymptote | Horizontal Shifts: Affect the x-values, do not change the horizontal asymptote.

Exponential: Variable in the exponent, constant percentage change | Linear: Variable in the base, constant additive change.

Growth Rate: Positive value, increases the function value | Decay Rate: Negative value (expressed in base), decreases the function value.

Both exponential growth and decay functions are concave up. However, growth increases rapidly, while decay decreases rapidly but remains above the x-axis.

Growth: $\lim_{x \to \infty} f(x) = \infty$ | Decay: $\lim_{x \to \infty} f(x) = 0$

Population Growth: Uses a positive growth rate, increases over time | Radioactive Decay: Uses a negative decay rate, decreases over time.

Domain: All real numbers | Range: $(0, \infty)$ for basic exponential functions without vertical shifts.

Simple Interest: Interest calculated only on the principal amount | Compound Interest: Interest calculated on the principal and accumulated interest.

$y = 2^x$: Exponential growth, increasing | $y = (1/2)^x$: Exponential decay, decreasing.

$f(x) = ab^x$

$f(x) = ab^x$, where $b > 1$

$f(x) = ab^x$, where $0 < b < 1$

$g(x) = f(x) + k$

$P(t) = P_0(1 + r)^t$, where $P_0$ is the initial population, r is the growth rate, and t is the time.

$A = P(1 + \frac{r}{n})^{nt}$, where A is the final amount, P is the principal, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

$N(t) = N_0e^{-\lambda t}$, where $N(t)$ is the amount remaining after time t, $N_0$ is the initial amount, and $\lambda$ is the decay constant.

$\lim_{x \to \infty} ab^x = \infty$ (when b > 1)

$\lim_{x \to \infty} ab^x = 0$ (when 0 < b < 1)

$\lim_{x \to -\infty} ab^x = 0$ (when b > 1)

If b > 1, the function represents exponential growth, increasing rapidly. If 0 < b < 1, the function represents exponential decay, decreasing rapidly.

A vertical shift moves the entire graph up or down. Adding a constant 'k' shifts the graph up if k > 0 and down if k < 0.

Limits describe the behavior of the function as x approaches infinity or negative infinity. Growth functions tend to infinity, while decay functions tend to zero as x approaches infinity.

Exponential functions are always either concave up (growth) or concave down (decay), so their concavity never changes, meaning no inflection points.

Exponential functions are always increasing or always decreasing; therefore, they do not have maximum or minimum values on an open interval.

Exponential functions are used to model situations with rapid growth or decay, such as population growth, compound interest, and radioactive decay.

The larger the base (b > 1), the faster the growth. The smaller the base (0 < b < 1), the faster the decay.

The y-intercept represents the initial value of the function when x = 0. It is the point where the function starts its growth or decay.

Since the domain is all real numbers, the function is defined for all values of x, allowing it to model continuous growth or decay over time.

Exponential decay functions are concave up. This means that the rate of decay decreases as x increases, but the function never changes direction.
